Skeleton Integral Equations for Acoustic Transmission Problems with Varying Coefficients
Francesco Florian, Ralf Hiptmair, Stefan A. Sauter
In this paper we will derive an non-local (``integral'') equation which transforms a three-dimensional acoustic transmission problem with \emph{variable} coefficients, non-zero abs…

A Stable Boundary Integral Formulation of an Acoustic Wave Transmission Problem with Mixed Boundary Conditions
Sarah Eberle, Francesco Florian, Ralf Hiptmair +1
In this paper, we consider an acoustic wave transmission problem with mixed boundary conditions of Dirichlet, Neumann, and impedance type. The transmission interfaces may join the…
