Laplacian eigenvalues for large negative Robin parameters on domains with outward peaks

Konstantin Pankrashkin, Firoj Sk, Marco Vogel

We study the asymptotic behavior of individual eigenvalues of the Laplacian in domains with outward peaks for large negative Robin parameters. A large class of cross-sections is al…

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…
