Spherical symmetry of some unitary invariants for commuting tuples
Our proof relies in particular on a number of properties of automorphic representations for unitary groups (including some multiplicity one results of Rogawski ...
Spectral Properties of Non-Unitary Band Matrices - Institut FourierAbstract. For a strongly continuous unitary representation of a Lie group G in a Hilbert space H we consider an analog of the Laplace operator L and use. Preliminary Facts About Unitary Groups in Three VariablesThe unitary representation theory of Aut(Td) goes back to [Ol'77] (see also [FN91]), and more generally, for subgroups H of Aut(Td) as above ... Spectral stability of unitary network models - Institut FourierWe will review the definition of the easy. ?noncommutative geometries? given there, using only the unitary group, the torus and the sphere, by taking into ...
