Title:A variational time discretization for Euler equations
Seminar:Hyperbolic and Mixed Type PDEs Seminar
Speaker:Fabio Cavalletti, Scuola Normale Superiore, Pisa
I will present a variational time discretization for the multi-dimensional gas dynamics equations, in the spirit of minimizing movements for curves of maximal slope. Each timestep requires the minimization of a functional measuring the acceleration of fluid elements, over the cone of monotone transport maps. We prove convergence to measure-valued solutions for the pressureless gas dynamics and the compressible Euler equations. This is a joint work with Marc Sedjro and Michael Westdickenberg.
