Crossed products of C*-algebras for singular actions
Hendrik Grundling, Karl-Hermann Neeb
We consider group actions of topological groups on C*-algebras of the types which occur in many physics models. These are singular actions in the sense that they need not be strong…
Positive definite superfunctions and unitary representations of Lie supergroups
Karl-Hermann Neeb, Hadi Salmasian
For a broad class of Frechet-Lie supergroups we prove that there exists a correspondence between positive definite smooth superfunctions and matrix coefficients of unitary represen…
Positive energy representations and continuity of projective representations for general topological groups
Karl-Hermann Neeb
Let and be topological groups, $α: T \to \Aut(G)$ a homomorphism defining a continuous action of on and the corresponding semidirect prod…
Differentiable vectors and unitary representations of Frechet-Lie supergroups
Hadi Salmasian, Karl-Hermann Neeb
For a locally convex Lie group with the Trotter property, we prove that the space of k-times differentiable vectors of a unitary representation is equal to the intersection of doma…
