Upper envelopes of families of Feller semigroups and viscosity solutions to a class of nonlinear Cauchy problems
Max Nendel, Michael Röckner
In this paper, we consider the (upper) semigroup envelope, i.e. the least upper bound, of a given family of linear Feller semigroups. We explicitly construct the semigroup envelope…

Regularity and asymptotic behaviour for a damped plate-membrane transmission problem
Bienvenido Barraza Martinez, Robert Denk, Jairo Hernandez Monzon +2
We consider a transmission problem where a structurally damped plate equation is coupled with a damped or undamped wave equation by transmission conditions. We show that exponentia…
