Monotonicity and the de Gennes bound for the magnetic Neumann Laplacian in the disk

Corentin Léna, Mikael Sundqvist

We consider the lowest eigenvalue of the magnetic Neumann Laplacian in the unit disk, for a constant magnetic field of strength . We prove that is strictly increasi…

Estimates for the lowest Neumann eigenvalues of parallelograms and domains of constant width

Corentin Léna, Jonathan Rohleder

We prove sharp upper bounds for the first and second non-trivial eigenvalues of the Neumann Laplacian in two classes of domains: parallelograms and domains of constant width. This…
