Semigroup estimates and fast-slow dynamics in parabolic-hyperbolic systems
Abstract
We present a general procedure to describe slow dynamics in parabolic-hyperbolic systems, under suitable assumptions on the terms appearing in the equations. In particular, our strategy relies in semigroup estimates for the evolution system associated to the family of time-dependent linearized operators around an interfaced configuration. We finally apply the general strategy to the explicit example of an hyperbolic system with relaxation.
