MVEX01-21-23 Geometric Numerical Integration of Differential Equations

​Ordinary differential equations (ODEs) arise everywhere in sciences and engineering: Newton’s law in physics, N-body problems in molecular dynamics or astronomy, populations models in biology, mechanical systems in engineering, etc. One can find analytical solutions to ODEs only in exceptional cases! It is therefore extremely important to rely on efficient numerical simulations of ODEs.

Many differential equations exhibit geometric properties that are preserved by the dynamics. Recently, there has been a trend towards the construction of geometric numerical integrators. Such numerical methods are of particular interest in long-term simulations of the outer solar system for instance.

The goal of the bachelor thesis is to provide students with a practical and accessible introduction to geometric numerical integration (GNI) of ODEs. This will be done by reading parts of the book "Geometric Numerical Integration" to understand the theory behind GNI and by testing novel numerical schemes on applications from celestial mechanics, molecular dynamics problems, or other applications of interest to the students.
