Abstract: Considering inhomogeneous and fully bi-anisotropic media necessary conditions have been identified for the diagonalizability of Maxwell's electrodynamic equations. The same conditions also ...

Abstract: A new source model, which consists of an intrinsic state part and an extrinsic observation part, is proposed and its information-theoretic characterization, namely its rate-distortion ...

This contribution is a review of the deep and powerful connection between the large-scale properties of critical systems and their description in terms of a field theory. Although largely applicable ...

Abstract: A set of quadratic forms is simultaneously diagonalizable via congruence (SDC) if there exists a basis under which each of the quadratic forms is diagonal. This property appears naturally ...

This section is about vector spaces and linear maps. We introduce the idea of a vector space, generalising sets of column vectors, and a linear map: a function between two vector spaces which ...

In this talk we shall begin with an introduction to Drinfeld cusp forms for arithmetic subgroups using Teitelbaum’s interpretation as harmonic cocycles. We shall then address the problem of the ...
