Graph Riemann problem


These lectures focus on the theory of nonlinear PDEs with particular emphasis on hyperbolic and degenerate parabolic problems. The main focus is on different notions of a solution (with representative examples) and on corresponding methods and techniques for studying well-posedness.

Topics are:

  • Hyperbolic and degenerate parabolic PDEs,
  • Quasilinear and fully nonlinear PDEs,
  • Porous medium equation,
  • Reaction-diffusion systems,
  • Different types of solutions (variational, entropy, renormalized, kinetic, ...),
  • Well-posedness,
  • Typical solutions and explicit solutions,
  • Approximation of solutions,
  • Stability of solutions and singular limits,
  • Nonlinear analysis techniques for PDEs.

The lectures give 10 LP.
At the end of the lecture period there will be the possibility of oral examinations. 

Neue Räume! Das Gebäude MAR ist in der neue gelbe TU-Bau in der Marchstrasse, „hinter“ dem Mathegebäude auf der anderen Strassenseite der Marchstrasse.
