Spectral isoperimetric inequalities for Robin Laplacians on 2-manifolds and unbounded cones

Magda Khalile, Vladimir Lotoreichik

We consider the problem of geometric optimization of the lowest eigenvalue for the Laplacian on a compact, simply-connected two-dimensional manifold with boundary subject to an att…

On Dirac operators in $R^{3}$ with electrostatic and Lorentz scalar $δ$ -shell interactions

Jussi Behrndt, Pavel Exner, Markus Holzmann +1

In this article Dirac operators $A_{η, τ}$ coupled with combinations of electrostatic and Lorentz scalar $δ$ -shell interactions of constant strength $η$ and $τ$ , respectively, supp…
