Fernando Lledó, Olaf Post

Motivated by the analysis of Schrödinger operators with periodic potentials we consider the following abstract situation: Let be the Laplacian on a non-compact Riemannian cov…

Duality of compact groups and Hilbert C*-systems for C*-algebras with a nontrivial center

Hellmut Baumgärtel, Fernando Lledó

In the present paper we prove a duality theory for compact groups in the case when the C*-algebra A, the fixed point algebra of the corresponding Hilbert C*-system (F,G), has a non…
