Martedì 31 Marzo 2015, alle ore 15 precise, il Dott. Fabio Cavalletti (Centro De Giorgi, SNS Pisa) terrà un seminario dal titolo:
"A Variational time discretization for the compressible Euler equations"
presso la sala conferenze dell'IMATI-CNR di Pavia.
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.
The Applied Mathematics Seminar usually meets on Tuesdays at 3 pm in the Conference Room of IMATI-CNR, Pavia. Refreshments are offered after the talk. For further information, please contact the organizers Carlo Lovadina, Stefano Lisini and Laura Spinolo.
