Parabolic partial differential equations are differential equations which depend on space and time. The heat equation and advection-diffusion-reaction equations are important members of that class. In this seminar we will analyse these problems and will treat numerical methods to solve such problems. Our focus lies on the combination of space and time discretization. Moreover, we will also consider eigenvalue problems and numerical methods to solve this kind of equations.

Students of mathematics (BSc and MSc) as well as students of scientific computing (MSc).

The seminar is in particular recommended for those students simultaneously taking the programming course *deal.II* or the lecture *Numerical analysis of partial differential equations*.

Numerical analysis of ordinary differential equations. Optionally: Numerics for PDEs and/or Analysis of PDEs.

For participation in the seminar you have to register via Müsli (binding registration).

Additionally, please write us a mail with your subject of study, semester, BSc / MSc, ... . Please also mention related lectures you have already attended, courses you will take in the winter term and, if you already have ideas, the area where you would like to write your thesis.
