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.

Normal forms of real symmetric systems with multiplicity

Abstract A normal form is given for real symmetric systems of linear partial differential equations, at points where the principal symbol has a two-dimensional kernel under assumptions which apply to

The multiplicity of eigenvalues

There are many examples of first order n x n systems of partial differential equations in 2 space variables with real coefficients which are strictly hyperbolic; that is, they have simple

Algebraic conditions for hyperbolicity of systems of partial differential equations

Partial differential equations or systems of such equations are classified according to “type”, such as “elliptic”, “parabolic”, “hyperbolic”, etc. Hyperbolic systems (with respect to the initial

This paper presents a meta-thesis on the basis of a model derived from the model developed in [Bouchut-Boyaval, M3AS (23) 2013] that states that the mode of action of the Higgs boson is determined by the modulus of the E-modulus.
