In his doctoral thesis, Mingchen Xia has approached the question of how to describe a spacetime vacuum through pluripotential theory.</b></p><p><img src="/SiteCollectionImages/Institutioner/MV/Nyheter/MingchenXia250x300.jpg" class="chalmersPosition-FloatRight" alt="Mingchen Xia" style="margin:5px" />The concept “spacetime” received its precise mathematical description in Albert Eninstein’s general theory of relativity, published just over a century ago. In this, the shape of the universe is described as a four-dimensional surface where the shape is determined by the matter content of space. The laws that govern the movement of spacetime can in mathematical terms be reduced to equations, called Einstein field equations.</p> <p>Mingchen Xia studies the geometry of the vacuum that would appear if all matter content of space would be removed. The problem is that the equations are nonlinear, which makes it difficult to find a direct solution. Several different approaches have been developed to obtain solutions, and one of the most recent is to use techniques from pluripotential theory where notions and special metrics from complex geometry and complex analysis are used.</p> <h2>Singular instead of regular functions</h2> <p>In the three articles of the thesis, the first deals with some open problems of the area. In the second, Mingchen has made use of the results from the first to gather conditions that guarantee the existence of the metrics, and in the third he explores what happens if there are no such metrics. The real innovation in the thesis is the applications of singular quasi-plurisubharmonic functions to the vacuum problem, whereas previously the emphasis has been on the regular functions.</p> <p>Mingchen’s interest for mathematics began when he was about ten years old, although he then did not know very much about it. He started to study more advanced mathematics and was most fascinated by the rigorous proofs and the structure behind it all. When he did his master’s studies in Paris all students were supposed to have an internship. His advisor suggested an available colleague as his future thesis advisor, who turned out to be Robert Berman in Gothenburg. After taking his master’s degree, Mingchen decided to come to Sweden for doctoral studies.</p> <h2>Great possibilities to do the research you want</h2> <p>– I did some research before, so I knew what to expect. Gothenburg has been a good place to live in and to do a PhD, although I do not like the winter! Compared to a big place like Paris there is a limited number of mathematicians if you are interested in a very specific topic, which can cause difficulties. But it is very cozy here and you have great possibilities to do the research you want, the advisors do not press too hard to make you go in a certain direction. In my opinion, to find the direction you want to go in yourself is one important part of being a PhD student.</p> <p>After the thesis defence, Mingchen is returning to Paris where he will have a postdoctoral position, financed by the Wallenberg Foundation.<br /><span style="background-color:initial"><br /><em>M</em></span><span style="background-color:initial"><em>i</em></span><span style="background-color:initial"><em>ngchen Xia will defend his PhD thesis “<a href="">Pluripotential-theoretic methods in K-stability and the space of Kähler metrics</a>” on October 5 at 14.30 in lecture hall Pascal, Hörsalsvägen 1.

This is the result of a collaboration between Chalmers researchers and surgeons at Sahlgrenska University Hosopital. Using augmented reality, surgeons are guided in real time during the operation.​</b></p>Operating on cancerous tumours of the liver is difficult for a number of reasons. The liver is an organ with many blood vessels, and liver tumours are usually embedded in the tissue. “The challenge is to locate the tumour and remove it with the right margins to save as much of the liver tissue as possible, which the patient needs to keep,” says Mårten Falkenberg, a surgeon at Sahlgrenska University Hospital, who helped develop the new technique. <h2 class="chalmersElement-H2"> Increased need for guidance</h2> <div>There are currently two established methods for liver surgery. One is open surgery, in which the abdominal cavity is opened so that the surgeon can look into the abdomen and feel the location of the tumour with their fingers to some extent. The other method is keyhole surgery. A camera is inserted through a hole in the abdominal wall, the surgeon’s instrument through another, and the surgeon works with the help of camera images on a screen. “We actually prefer keyhole surgery because it’s less invasive for the patient, but the ability to feel the tumour with your fingers disappears, which increases the need for guidance to show you where it is,” says Mårten Falkenberg. Navigating by camera images alone is difficult. The liver is a homogeneous organ. It simply looks almost the same from different angles. This is where the new technique comes in. A 3D scan of the liver is already standard before surgery. The idea was developed by researchers including Torbjörn Lundh and Klas Modin at the Department of Mathematical Sciences at Chalmers University of Technology and is based on enhancing the images that are taken. <img src="/SiteCollectionImages/Institutioner/MV/Nyheter/Navari/KModin-portr.gif" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:185px;height:185px" /><br /><br /></div> <div> “We use augmented reality, based on the pre-operative scan and newly developed algorithms, to produce an image of what the tumour looks like and where it is located. This image is superimposed on the camera image that the surgeons see during the operation, as a guide for how to cut to get the tumour out,” says Klas Modin.</div> <h2 class="chalmersElement-H2"> Making use of existing information</h2> <div> The particular feature of this technology is that it is based on existing information and technical equipment. Images based on the pre-operative scan are displayed in real time as a layer on top of the camera images during the operation. After having attended a liver operation at Sahlgrenska University Hospital, Klas Modin and Torbjörn Lundh applied this experience when they worked on their proposal. One thing that made a strong impression was that there is already a great deal of technical equipment in the operating theatre, and large amounts of information are constantly being shared. <img src="/SiteCollectionImages/Institutioner/MV/Nyheter/Navari/TLundh-portr.gif" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:185px;height:185px" /><br /><br /></div> <div> “Based on how operations are currently performed, with the aim of being minimally invasive, i.e. keyhole surgery, we want to contribute a solution that is also minimally invasive in terms of the surgeons’ working environment,” says Torbjörn Lundh. </div> <div><br /></div> <h3 class="chalmersElement-H3"><br /></h3> <h3 class="chalmersElement-H3">More about the research</h3> <div>The research behind the method began in 2016.

Digital twins can be used to generate synthetic data to train AI systems efficiently without the need to collect real world data and annotating them manually which is costly, slow, noisy and error prone. <br /></div> <div><span style="background-color:initial">Researcher: </span><a href="/en/staff/Pages/dubhashi.aspx">Devdatt Dubhashi </a></div> <div><br /></div> <div><span style="background-color:initial">Project: </span><strong style="background-color:initial">Dpella</strong><br /></div> <div>The world is collecting a massive amount of individuals data with the intention of building a human-centered future based on data insights.

In this way, a more comprehensive view of how cells accumulate damages and age has emerged</b></p><p>​As the world population gets increasingly older, we need to understand how to avoid age-related diseases. One important part of this is to understand ageing on a cellular level. Research on cells is usually done through experiments in a laboratory, and in that way a lot of isolated processes in the cells have been analysed. But the cell ageing is also characterised by the interactions of these processes, and the interactive and multi-scale dimensions are not always possible to study in a laboratory environment. To get a broader insight on how cells age, this project has been using mathematics in the form of different models for different cellular processes closely connected to ageing.</p> <h2>Mathematical models to describe cellular processes</h2> <p>The three chosen processes are the signalling system, which is able to sense changes in the cellular environment; the metabolism, which converts food into energy; and damage accumulation, which defines ageing in Barbara’s project. Depending on the available details of the biology, these networks have been translated into Boolean models, optimisation models (so-called flux balance analysis), and ordinary differential equations.</p> <p><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/MV/Nyheter/BarbaraSchnitzer250x300.jpg" alt="" style="margin:5px" />– All models have been combined to get an understanding of how the processes interact, since this interaction is important when the cell loses its function. The results are different predictions and suggestions on how these interactions work. The next step would be for the biologists to take, through verification experiments in the laboratory. The results can also be further built upon through adding more cellular processes and defining the connections between them.</p> <h2>Erasmus exchange led to Gothenburg</h2> <p>Barbara’s Bachelor degree, which she took in Germany, was neither in mathematics nor biology but in physics. She went to the University of Gothenburg in a six-month Erasmus exchange and there found the Master programme Complex Adaptive Systems which appealed to her. The programme included courses in computational biology, and when doing her Master’s thesis the PhD position that Barbara has had turned up. For the last two years she has worked closely to PhD Linnea Österberg, an experimentalist and biologist working in the same project group who defended her thesis on April 29. From the beginning they had separate projects, but the cooperation evolved naturally and they have had the benefit of going through the PhD work together.</p> <p>– A highlight during these years was when we gave a popular science talk called “A mathematician and a biologist walk into a bar” (<a href="">En matematiker och en biolog går in i en bar</a>, on UR Play) during the International Science Festival Gothenburg. Since it was in the year of 2021 it was digital, sent live from a studio, which was an interesting experience even if I was nervous. I think it is important for scientists to be able to explain what we do.</p> <p>Barbara has liked living in Gothenburg and finds the PhD conditions in Sweden good, since it is like a normal job with a secure employment and fixed salary. In the beginning she lived with a Swedish girl and chose to speak Swedish all the time, which together with some courses gave her a good knowledge of the language. The research language is however always English, so it is easier to talk about work in English. Barbara has also taught courses, mostly basic mathematics courses but also a master’s course. She found it hard in the beginning but kind of grew into it, and now sees it as a nice experience. Now, she will start looking for a job in industry.</p> <p><em>Barbara Schnitzer will defend her PhD thesis “</em><a href=""><em>Mathematical Modelling of Cellular Ageing: A Multi-Scale Perspective</em></a><em>” on May 13 at 10.15 in lecture hall Pascal, Hörsalsvägen 1, and via Zoom.

However, most real numbers cannot be expressed in this manner – they are irrational. The best-known irrational numbers include π and the square root of two, √2. How these irrational numbers should be best approximated using rational numbers has, in its simplest form, been well understood for more than a century. The field of diophantine approximation, which this project is about, examines how well an approximation can be performed using rational numbers for a given real number.<br /><br /> One way of approaching the question is to calculate the number of rational numbers that provide good approximations to a given real number and which have denominators below a specified high limit. It has been known since the 1960s that, for almost all real numbers, their quantity grows towards infinity at an almost exactly logarithmic rate with the given limit for the denominator. Deviations from this rate fulfil a specific form of the central limit theorem, i.e. a normal distribution, as recently proven by Michael Björklund and Alexander Gorodnik. <br /><br /> The purpose of the project is, in the next step, to move beyond the normal distribution. The basis for understanding deviations from the normal distribution is the already well-known analysis of the sums of independent random variables and the central limit theorem. In the case being studied, the random variables are only partially independent, but the analogy may bear fruit and lead to better estimations that those now known. <br /></div> <h2 class="chalmersElement-H2">The shape of the universe</h2> <img src="/SiteCollectionImages/Institutioner/MV/Nyheter/KAW%202021/Mingchen-Xia-Chalmers.gif" class="chalmersPosition-FloatRight" alt="Mingchen Xiao" style="margin:5px;width:225px;height:192px" /> <div><a href="/en/staff/Pages/xiam.aspx">Mingchen Xia, PhD student</a> in the Division for Algebra and Geometry, Department of Mathematical Sciences, receives funding for a postdoctoral position with Professor Sébastien Boucksom at the École Polytechnique, Palaiseau, France. </div> <div><br /></div> <div>Time and space shape our universe. The theory of how they are connected was developed in the eighteenth century by Isaac Newton. However, in his Principia Matematica, time and three-dimensional space are independent. They were first linked in a shared spacetime almost 200 years later, when James Clerk Maxwell realised that the speed of light in a vacuum was constant, regardless of who measured it. This was only possible if space and time were regarded as a unity – a spacetime. </div> <div><br /></div> <div> Spacetime received its precise mathematical description in Albert Einstein’s masterpiece – the general theory of relativity, which was published just over a century ago. The theory describes the shape of the universe as a four-dimensional surface. Its shape is determined by the matter content of space – the more matter, the more curved the surface. But what is the shape of the universe if all matter is removed, how can a vacuum be described? If there is nothing at all, is the universe then entirely flat? The answer was astounding – it turns out that the theory of relativity actually permits many non-flat vacua. </div> <div><br /></div> <div> In the theory of relativity, the exact relationship between matter and the shape of the cosmos is given a set of differential equations, Einstein’s field equations. These are notoriously difficult to solve and several different approaches have been developed over the past century to obtain direct solutions for spacetime. One of the most recent is pluripotential theory, an area within complex mathematical analysis. The plan is to use these methods to help explore the intricate geometry of the vacuum. </div> <h2 class="chalmersElement-H2">About the Knut and Alice Wallenberg Foundation program for mathematics</h2> <div><span style="background-color:initial">Over the years 2014–2029, the program will provide SEK 650 million to allow Swedish researchers to receive international postdoctoral positions, as well as the international recruitment of visiting professors and of foreign researchers to postdoctoral positions at Swedish universities.

Now, a new article in Nature Communications, written by researchers from Chalmers University of Technology, Sweden, and MIT, USA, presents results that cast new light on important challenges in understanding quantum gravity.</b></p>A grand challenge in modern theoretical physics is to find a ‘unified theory’ that can describe all the laws of nature within a single framework – connecting Einstein's general theory of relativity, which describes the universe on a large scale, and quantum mechanics, which describes our world at the atomic level. Such a theory of ‘quantum gravity’ would include both a macroscopic and microscopic description of nature.<div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MV/Nyheter/Nature%202022/Daniel-Persson.gif" class="chalmersPosition-FloatRight" alt="Daniel Persson" style="margin:5px;width:200px;height:300px" /> “We strive to understand the laws of nature and the language in which these are written is mathematics. When we seek answers to questions in physics, we are often led to new discoveries in mathematics too. This interaction is particularly prominent in the search for quantum gravity – where it is extremely difficult to perform experiments,” explains Daniel Persson, Professor at the Department of Mathematical Sciences at Chalmers university of technology.</div> <div><br /></div> <div> An example of a phenomenon that requires this type of unified description is black holes. A black hole forms when a sufficiently heavy star expands and collapses under its own gravitational force, so that all its mass is concentrated in an extremely small volume. The quantum mechanical description of black holes is still in its infancy but involves spectacular advanced mathematics.</div> <div><br /></div> <h2 class="chalmersElement-H2"> A simplified model for quantum gravity</h2> <div><img src="/SiteCollectionImages/Institutioner/MV/Nyheter/Nature%202022/Robert-Berman.gif" alt="Robert Berman" class="chalmersPosition-FloatLeft" style="margin:5px;width:200px;height:265px" />“The challenge is to describe how gravity arises as an ‘emergent’ phenomenon. Just as everyday phenomena – such as the flow of a liquid – emerge from the chaotic movements of individual droplets, we want to describe how gravity emerges from quantum mechanical system at the microscopic level,” says Robert Berman, Professor at the Department of Mathematical Sciences at Chalmers University of Technology.</div> <div><br /></div> <div> In an article recently published in the journal Nature Communications, Daniel Persson and Robert Berman, together with Tristan Collins of MIT in the USA, showed how gravity emerges from a special quantum mechanical system, in a simplified model for quantum gravity called the ‘holographic principle’.</div> <div><br /></div> <div>“Using techniques from the mathematics that I have researched before, we managed to formulate an explanation for how gravity emerges by the holographic principle, in a more precise way than has previously been done,” explains Robert Berman.</div> <h2 class="chalmersElement-H2"> Ripples of dark energy</h2> <div> The new article may also offer new insight into mysterious dark energy. In Einstein's general theory of relativity, gravity is described as a geometric phenomenon. Just as a newly made bed curves under a person's weight, heavy objects can bend the geometric shape of the universe. But according to Einstein's theory, even the empty space – the ‘vacuum state’ of the universe – has a rich geometric structure. If you could zoom in and look at this vacuum on a microscopic level, you would see quantum mechanical fluctuations or ripples, known as dark energy. It is this mysterious form of energy that, from a larger perspective, is responsible for the accelerated expansion of the universe.</div> <div><br /></div> <div>This new work may lead to new insights into how and why these microscopic quantum mechanical ripples arise, as well as the relationship between Einstein's theory of gravity and quantum mechanics, something that has eluded scientists for decades.</div> <div><br /></div> <div>“These results open up the possibility to test other aspects of the holographic principle such as the microscopic description of black holes. We also hope to be able to use these new connections in the future to break new ground in mathematics,” says Daniel Persson.</div> <div><br /></div> <div> The scientific article, <a href="">Emergent Sasaki-Einstein geometry and AdS/CFT</a>, is published in Nature Communications and is written by Robert Berman, Tristan Collins and Daniel Persson at Chalmers University of Technology, Sweden, and Massachusetts Institute of Technology, USA. </div> <h3 class="chalmersElement-H3">For more information, contact:</h3> <div> Daniel Persson, Professor, Department of Mathematical Sciences, Chalmers university of Technology and University of Gothenburg <br /><a href=""></a> <br />+46 31 772 3174</div> <div><br /></div> <div>Robert Berman, Professor, Department of Mathematical Sciences, Chalmers university of Technology and University of Gothenburg</div> <div><a href=""></a> </div> <div>+46 31 772 3553   </div> <div><br /></div> <div>Text: Joshua Worth</div> <div>Photo: Anna Wallin (Daniel Persson) and Rakel Berman (Robert Berman)</div> ​​​Mon, 07 Mar 2022 14:00:00 +0100öran Gustafsson Prize to David Witt Nyström<p><b>​David Witt Nyström, Associate Professor at the University of Gothenburg, receives the mathematics prize “for his deep and innovative work in complex analysis with important applications in complex and algebraic geometry”.</b></p>​<p><img width="250" height="297" class="chalmersPosition-FloatRight" alt="David Witt Nyström" src="/SiteCollectionImages/Institutioner/MV/Nyheter/DavidWittNystrom_Foto_Privat250.jpg" style="margin:5px" />In algebraic geometry, the study objects are curves, surfaces and object of higher dimensions (so-called manifolds) that have in common that they are defined with the help of polynomials. One example is the circle, which can be described as the points in the plane where the polynomial x^2+y^2-1 is zero. Although the circle is easy to understand, manifolds of this kind can be extremely intricate, especially in higher dimensions.</p> <p>The specific research area for David Witt Nyström, Kähler geometry, focuses on how a manifold’s small-scale form, its curvature, is related to its large-scale form, its topology. In addition to algebraic methods this demands advanced tools from complex analysis.</p> <p>David Witt Nyström has, among other things, proved a conjecture (proposition) well-known in the area. It describes how, in a specific context, global topological data are determined by local curvature properties.</p> <p>Another major track in his research is the Hele-Shaw flow, which describes how a viscous liquid moves in a thin layer. There, an unexpected connection to Kähler geometry led to a much discussed counterexample to a well-known conjecture.</p> <p>– I am incredibly happy and honoured to have been awarded the Göran Gustafsson Prize, and it will clearly be of great importance for my further research, he says.</p> <p><strong>Text and photo</strong>: from the page of the <a href="">Royal Swedish Academy of Sciences, read more about the prize and the prize winners in other subjects (in Swedish) &gt;&gt;</a></p>Fri, 04 Mar 2022 15:30:00 +0100​Time to inaugurate all-wise computer resource<p><b>​Alvis is an old Nordic name meaning &quot;all-wise&quot;.
