Crossed products of C^*-algebras for singular actions with spectrum conditions
Hendrik Grundling, Karl-Hermann Neeb
We analyze existence of crossed product constructions of Lie group actions on C^*-algebras which are singular. These are actions where the group need not be locally compact, or the…
Reflection negative kernels and fractional Brownian motion
P. Jorgensen, K. -H. Neeb, G. Olafsson
In this article we study the connection of fractional Brownian motion, representation theory and reflection positivity in quantum physics. We introduce and study reflection positiv…
Reflection Positivity---A Representation Theoretic Perspective
Karl-Hermann Neeb, Gestur Olafsson
Refection Positivity is a central theme at the crossroads of Lie group representations, euclidean and abstract harmonic analysis, constructive quantum field theory, and stochastic…
Multiplicity freeness of unitary representations in sections of holomorphic Hilbert bundles
Martin Miglioli, Karl-Hermann Neeb
We prove several results asserting that the action of a Banach-Lie group on Hilbert spaces of holomorphic sections of a holomorphic Hilbert space bundle over a complex Banach manif…
