Plummeting and blinking eigenvalues of the Robin Laplacian in a cuspidal domain

Sergei A. Nazarov, Nicolas Popoff, Jari Taskinen

We consider the Robin Laplacian in the domains $Ω$ and $Ω^{ε}$ , $ε > 0$ , with sharp and blunted cusps, respectively. Assuming that the Robin coefficient $a$ is lar…

"Blinking eigenvalues" of the Steklov problem generate the continuous spectrum in a cuspidal domain

Sergei A. Nazarov, Jari Taskinen

We study the Steklov spectral problem for the Laplace operator in a bounded domain $Ω \subset R^{d}$ , $d \geq 2$ , with a cusp such that the continuous spectrum of the problem…
