SUMMARY:Entire solutions to equivariant elliptic systems with variational structure
DESCRIPTION:We consider an elliptic system with variational structure. After making some general remarks\,  we focus on potentials that possess several global minima and are invariant under  a finite reflection group G.  We establish existence of G-equivariant entire solutions connecting the global minima.

SUMMARY:Rigorous stability/bifurcation analysis for strong detonation waves
DESCRIPTION:We present recent results with B. Texier developing a rigorous nonlinear theory of stability and bifurcation of strong detonation waves of the full reacting Navier-Stokes (rNS) equations\, based on natural spectral stability/bifurcation conditions.  We discuss in parallel recent singular perturbation results showing that in the small viscosity limit these conditions reduce to the corresponding conditions for the ZND\, or reacting Euler\, equations that are more commonly studied in the detonation literature.  This yields immediately numerical verification of the (rNS) conditions through the voluminous numerical literature on (ZND).
