C-submodule preserving module mappings on Hilbert C-modules

Michael Frank

Let $A$ be a (non-unital, in general) C*-algebra with center $Z (M (A))$ of its multiplier algebra, and let ${X, ⟨ ., . ⟩}$ be a full Hilbert $A$ -module. Then any bije…

Hilbert C*-modules from group actions: beyond the finite orbits case

M. Frank, V. Manuilov, E. Troitsky

Continuous actions of topological groups on compact Hausdorff spaces $X$ are investigated which induce almost periodic functions in the corresponding commutative C*-algebra. The un…
