Peculiar behavior of the principal Laplacian eigenvalue for large negative Robin parameters

Charlotte Dietze, Konstantin Pankrashkin

Let $Ω \subset R^{n}$ with $n \geq 2$ be a bounded Lipschitz domain with outer unit normal $ν$ . For $α \in R$ let $R_{Ω}^{α}$ be the Laplacian in $Ω$ with the Robin boundary…

Laplacian eigenvalues with a large negative Robin parameter on a part of the boundary

Konstantin Pankrashkin

We consider the Laplacian eigenvalues for smooth planar domains with strongly attractive Robin conditions imposed on a part of the boundary and Neumann condition on the remaining b…
