On the decay rate for the wave equation with viscoelastic boundary damping
Reinhard Stahn
We consider the wave equation with a boundary condition of memory type. Under natural conditions on the acoustic impedance of the boundary one can define a corresponding…

Existence of solutions for semilinear elliptic boundary value problems on arbitrary open sets
Reinhard Stahn
We show the existence of a weak solution of a semilinear elliptic Dirichlet problem on an arbitrary open set. We make no assumptions about the open set, very mild regularity assump…
