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…
An asymptotic shape optimization problem for Riesz means of Laplacian eigenvalues
Rupert L. Frank, Simon Larson
We review our recent results on the problem of optimizing Riesz means of Laplace eigenvalues among convex sets of given measure in the regime where the cut-off parameter in the def…
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…
Uniform bounds for Neumann heat kernels and their traces in convex sets
Rupert L. Frank, Simon Larson
We prove a bound on the heat trace of the Neumann Laplacian on a convex domain that captures the first two terms in its small-time expansion, but is valid for all times and depends…
A Jensen inequality for partial traces and applications to partially semiclassical limits
Eric A. Carlen, Rupert L. Frank, Simon Larson
We prove a matrix inequality for convex functions of a Hermitian matrix on a bipartite space. As an application we reprove and extend some theorems about eigenvalue asymptotics of…
Improved semiclassical eigenvalue estimates for the Laplacian and the Landau Hamiltonian
Rupert L. Frank, Simon Larson, Paul Pfeiffer
The Berezin--Li--Yau and the Kröger inequalities show that Riesz means of order of the eigenvalues of the Laplacian on a domain of finite measure are bounded in terms…
Spectral asymptotics for Robin Laplacians on Lipschitz sets
Rupert L. Frank, Simon Larson
We prove two-term spectral asymptotics for the Riesz means of the eigenvalues of the Laplacian on a Lipschitz domain with Robin boundary conditions. The second term is the same as…
Semiclassical inequalities for Dirichlet and Neumann Laplacians on convex domains
Rupert L. Frank, Simon Larson
We are interested in inequalities that bound the Riesz means of the eigenvalues of the Dirichlet and Neumann Laplacians in terms of their semiclassical counterpart. We show that th…
Riesz means asymptotics for Dirichlet and Neumann Laplacians on Lipschitz domains
Rupert L. Frank, Simon Larson
We consider the eigenvalues of the Dirichlet and Neumann Laplacians on a bounded domain with Lipschitz boundary and prove two-term asymptotics for their Riesz means of arbitrary po…
