First Order Symbols on Surfaces and their multiplicity sets

10 Feb 2020  ·  Valero Carlos ·

We study the multiplicity sets of first order symbols associated with differential operators on two dimensional surfaces. This work is inspired by the phenomenon of conical refraction explained by the existence of singularities in the Fresnel hyper-surface for Maxwell's equations on an anisotropic crystal...
