The diamagnetic inequality for the Dirichlet-to-Neumann operator

. A. F. M. ter Elst, El Maati Ouhabaz

Let $\Omega$ be a bounded domain in R d with Lipschitz boundary $\Gamma$. We define the Dirichlet-to-Neumann operator N on L 2 ($\Gamma$) associated with a second order elliptic operator A = -- d…
