The interior transmission problem and bounds on transmission eigenvalues
Michael Hitrik, Katsiaryna Krupchyk, Petri Ola +1
We study the interior transmission eigenvalue problem for sign-definite multiplicative perturbations of the Laplacian in a bounded domain. We show that all but finitely many comple…
Transmission eigenvalues for elliptic operators
Michael Hitrik, Katsiaryna Krupchyk, Petri Ola +1
A reduction of the transmission eigenvalue problem for multiplicative sign-definite perturbations of elliptic operators with constant coefficients to an eigenvalue problem for a no…
Transmission eigenvalues for operators with constant coefficients
Michael Hitrik, Katsiaryna Krupchyk, Petri Ola +1
In this paper we study the interior transmission problem and transmission eigenvalues for multiplicative perturbations of linear partial differential operator of order with…
