Unitary representations of compact quantum groups
Raluca Dumitru
Let v be the right regular representation of a compact quantum group G. Then (S.L.Woronowicz, "Compact quantum groups") v contains all irreducible representations of G and each irr…

Compact quantum group actions on C*-algebras and invariant derivations
R. Dumitru, C. Peligrad
We define the notion of invariant derivation of a C*-algebra under a compact quantum group action and prove that in certain conditions, such derivations are generators of one param…

Automorphisms Inner in the Local Multiplier Algebra and Connes Spectrum
Raluca Dumitru, Costel Peligrad, Bogdan Visinescu
We obtain some results that relate the Connes spectrum with the innerness of automorphisms in the fixed point local multiplier algebra. The results are variants and/or extensions o…
