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
