M-dissipative boundary conditions and boundary tuples for Maxwell operators

For Maxwell operators in Lipschitz domains, we describe all m-dissipative boundary conditions and apply this result to generalized impedance Leontovich including the cases of singular, degenerate, randomized coefficients. To end construct Riesz bases trace spaces associated with curl-operator introduce a modified version triple adapted specifics equations, namely, mixed-order duality related spaces. This provides translation problem operator-theoretic settings abstract operators. In particular, show that Calkin reduction are naturally connected provide an condition applicable other types wave equations. Taking Friedrichs Krein-von Neumann extensions operators, it is possible associate arbitrary non-negative measurable
