An indefinite Laplacian on a rectangle
Original language description
We investigate a nonelliptic differential expression on a rectangular domain in the plane. The seemingly simple problem of associating a self-adjoint operator with the differential expression in the Hilbert space of square-integrable functions is solved here. Such indefinite Laplacians arise in mathematical models of metamaterials characterized by negative electric permittivity and/or negative magnetic permeability.
