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…

Schauder bases and the decay rate of the heat equation

José Bonet, Wolfgang Lusky, Jari Taskinen

We consider the classical Cauchy problem for the linear heat equation and integrable initial data in the Euclidean space $R^{N}$ . In the case $N = 1$ we show that given a weig…
