Abstract:
We provide examples of sustained oscillations for hyperbolic-parabolic systems. The existence of sustained oscillations in hyperbolic-parabolic system is studied systematically via examples, for paradigm systems from viscoelasticity and for the compressible Navier-Stokes system with non-monotone pressures. In several space dimensions oscillatory examples are associated with lack of rank-one convexity of the stored energy. The subject naturally leads to the problem of deriving effective equations for the associated homogenization problems. We address that in a context of a simple one-dimensional model be addressed by employing ideas from the kinetic formulation for conservation laws.
