Essential Spectrum for Maxwell`s Equations
Abstract:
We study the essential spectrum of operator pencils associated with anisotropic Maxwell equations with conductivity on finitely connected unbounded domains. The main result is that the essential spectrum of the Maxwell pencil is the union of two sets: namely, the spectrum of a divergence form operator pencil, and the essential spectrum of the Maxwell pencil with constant coefficients. This is joint work with G.Alberti, M.Brown and M.Marletta.
