On the nonexistence of transmission eigenvalues for regions with cavities. (English) Zbl 1231.35136

Authors’ abstract: We consider the interior transmission problem when the inhomogeneous medium has a cavity region. In this case we establish the Fredholm property for this problem and show that there does not exist a transmission eigenvalue under a new condition.
