Analysis and Probability Seminar

The seminar is joint for the division of Analysis and Probability and its main themes are Mathematical Physics, Probability Theory and Harmonic and Functional Analysis. The seminar is encouraged to be aimed at a broader audience, but some talks may be of a more specialised nature. The talks in the seminar are usually 60 minutes, including questions.

The seminar gradually returns to campus with possibility to attend online via Zoom (subject to technology working). See schedule below for links to Zoom meetings.

Should you have any questions or suggestions, feel free to email one of the organizers Jakob Björnberg (jakobbj 'at', Probability Theory), Erik Broman (broman 'at', Probability Theory) or Clemens Weiske (weiske 'at', Analysis).

About branching problems for holomorphic discrete series
In this talk I am going to present branching problems for some representations of Lie groups which are some members of the so-called holomorphic discrete series. After presenting the motivations, I will present an example of such branching problem with the decomposition of the n-fold tensor product of holomorphic discrete series of SL2(R). This example will allows me to exhibit a link between this branching problem and the study of some orthogonal polynomials on the n-1 dimensional simplex.

L^p-stability and positive scalar curvature rigidity of Ricci-flat ALE manifolds
We prove stability of integrable ALE manifolds with a parallel spinor under Ricci flow, given an initial metric which is close in $L^p\cap L^{\infty}$ for some $p\in (1,\infty), where n is the dimension of the manifold. In particular, our result applies to all known examples of 4-dimensional gravitational instantons. The result is obtained by a fixed point argument, based on novel estimates for the heat kernel of the Lichnerowicz Laplacian. It allows us to give a precise description of the convergence behaviour of the RIcci flow. Our decay rates are strong enough to prove positive scalar curvature rigidity in $L^p$ for each $p\in [1,\frac{n}{n-2})$, generalizing a result by Appleton. This is joint work with Oliver Lindblad Petersen.
