On automorphisms of C*-algebras whose Voiculescu entropy is genuinely noncommutative
Adam Skalski
We use the results of Neshveyev and Stormer to show that for a generic shift on a C*-algebra associated to a bitstream the Voiculescu topological entropy is strictly larger that th…
A New Characterisation of Idempotent States on Finite and Compact Quantum Groups
Uwe Franz, Adam Skalski
We show that idempotent states on finite quantum groups correspond to pre-subgroups in the sense of Baaj, Blanchard, and Skandalis. It follows that the lattices formed by the idemp…
Convolution semigroups of states
J. Martin Lindsay, Adam Skalski
Convolution semigroups of states on a quantum group form the natural noncommutative analogue of convolution semigroups of probability measures on a locally compact group. Here we i…
Idempotent states on compact quantum groups and their classification on U_q(2), SU_q(2), and SO_q(3)
Uwe Franz, Adam Skalski, Reiji Tomatsu
Unlike for locally compact groups, idempotent states on locally compact quantum groups do not necessarily arise as Haar states of compact quantum subgroups. We give a simple charac…
