Spectral ratios and gaps for Steklov eigenvalues of balls with revolution-type metrics

Jade Brisson, Bruno Colbois, Katie Gittins

We investigate upper bounds for the spectral ratios and gaps for the Steklov eigenvalues of balls with revolution-type metrics. We do not impose conditions on the Ricci curvature o…

A reverse Faber-Krahn inequality for the magnetic Laplacian

Bruno Colbois, Corentin Léna, Luigi Provenzano +1

We consider the first eigenvalue of the magnetic Laplacian in a bounded and simply connected planar domain, with uniform magnetic field and Neumann boundary conditions. We investig…

Some recent developments on the Steklov eigenvalue problem

Bruno Colbois, Alexandre Girouard, Carolyn Gordon +1

The Steklov eigenvalue problem, first introduced over 125 years ago, has seen a surge of interest in the past few decades. This article is a tour of some of the recent developments…
