Decay rates for damped wave equations

Abstract: In this talk I will present some recent results about the decay of wave equations with visco-elastic dampings. 

I will in particular highlight the convergences and differences between this kind of damping and the more classical ones, in terms of

— Propagation of singularities

— Overdamping phenomena (too much damping kills the damping”

— Boundary value problems analysis”

This is based on joint works with Chenmin Sun (University of Cergy-Pontoise
