Robin counting functions on cuboids in the critical scaling regime

Matthias Baur, Simon Larson

We consider eigenvalue counting functions of Robin Laplace operators on cuboids where the Robin parameter and the spectral cut-off are coupled. Our main focus is the critical r…

Optimizing Riesz means of Robin Laplace operators on cuboids in a semiclassical limit

Matthias Baur, Simon Larson

We study asymptotic shape optimization for Riesz means of Robin Laplacian eigenvalues among cuboids of fixed measure. Our focus is the regime where the Robin parameter is proportio…
