On Pleijel's nodal domain theorem for the Robin problem

Asma Hassannezhad, David Sher

We prove an improved Pleijel nodal domain theorem for the Robin eigenvalue problem. In particular we remove the restriction, imposed in previous work, that the Robin parameter be n…

Nodal count for Dirichlet-to-Neumann operators with potential

Asma Hassannezhad, David Sher

We consider Dirichlet-to-Neumann operators associated to $Δ + q$ on a Lipschitz domain in a smooth manifold, where $q$ is an $L^{\infty}$ potential. We prove a Courant-type bound for…
