>Title:  Relaxation-based approximate Riemann solvers for compressible flows
>I will present new numerical methods for the Euler equations and the 
>ideal MHD (magnetohydrodynamics) equations. These methods satisfy 
>two important stability criteria: They preserve positivity of 
>density and pressure, and satisfy a discrete entropy inequality. The 
>talk will focus on (i) A numerical study for compressible high Mach 
>number flows, including isotropic turbulence, and (ii) The extension 
>of the approach to MHD. The results are from joint work with 
>Francois Bouchut, Christian Klingenberg and
>Wolfram Schmidt.
