Upper bounds for the Steklov eigenvalues of warped products

Jade Brisson, Bruno Colbois, Alexandre Girouard +1

We obtain upper bounds for the Steklov eigenvalues of warped products $Ω \times_{h} Σ$ , where $Ω$ is a compact Riemannian manifold with boundary and $Σ$ is a closed Riemannian manifold…

Magnetic ground states and the conformal class of a surface

Bruno Colbois, Luigi Provenzano, Alessandro Savo

On a closed, orientable Riemannian surface $Σ_{g}$ of arbitrary genus $g \geq 1$ and Riemannian metric $h$ we study the magnetic Laplacian with magnetic potential given by a harmonic…
