Sharp spectral estimates in domains of infinite volume

Leander Geisinger, Timo Weidl

We consider the Dirichlet Laplace operator on open, quasi-bounded domains of infinite volume. For such domains semiclassical spectral estimates based on the phase-space volume - an…

Geometrical Versions of improved Berezin-Li-Yau Inequalities

Leander Geisinger, Ari Laptev, Timo Weidl

We study the eigenvalues of the Dirichlet Laplace operator on an arbitrary bounded, open set in $R^{d}$ , $d \geq 2$ . In particular, we derive upper bounds on Riesz means of order $σ…
