Low Mach

The (typically bad) performance of methods for compressible flow in the low Mach number regime is both an interesting (for mathematicians) and pressing (for simulators) problem. My work focuses on the asymptotics for the Euler equations and deals with the analysis of modifications to the upwinding matrices in Roe-type schemes and with multi-d solvers.
