M2 MF — Numerics for transport

Master 2 in Fundamental Mathematics

The lecture (24h) will be given during fall 2025 for the students of the Master 2 in Fundamental Mathematics (french website). The first sessions take place on Wednesday, November 12. 2025. The complete schedule is available on ADE.

Abstract

This course aims to study the various numerical strategies of approximation of solutions to evolution partial differential equations. Finite difference methods are analyzed through a symbolic approach. This approach allows to revisit the traditional convergence study from a frequency point of view. We will see how to explain and improve the “physics” of the numerical solutions via properties of the discrete dispersion relation. We will quickly tackle spectral and pseudo-spectral methods. In the second part of the course, we will study finite volume strategies. They will be analyzed mainly for the approximation of weak entropy solutions of hyperbolic scalar conservation laws in one space dimension.
