Compact Course on Mathematical aspects of stochastic Compressible Fluid Flows

Dates : February 17 - February 28, 2020
Venue : TIFR Center for Applicable Mathematics, Bangalore



Martina Hofmanova
Faculty of Mathematics
Bielefeld University

Martina Hofmanova is a young Professor of Mathematics in the Bielefeld University of Germany. She is a renowned specialist in the mathematical theory of stochastic fluid dynamics, in particular stochastic Navier Stokes and Euler equations. She is also an expert on rough path theory for stochastic partial di erential equations.


We introduce our model system and main questions of interest. A particular emphasis is put on various notions of solutions. To begin, we briefly discuss the principal concepts from probability theory and stochastic analysis with applications to stochastic PDEs, and make a short excursion in the theory of compressible Navier-Stokes equations. As the first step in our analysis of the compressible Navier-Stokes system driven by stochastic forces we establish existence of a dissipative martingale solution. We also show that they satisfy a relative energy inequality and discuss the long time behaviour of dissipative martingale solutions. Next, we prove existence of strong solutions. These solutions are strong in the PDE and probabilistic sense and can only be showed to exist locally in time, that is, up to a positive stopping time.
