A cocycle for the comultiplication on the quantum SU(2) group
Wojciech Szymanski
For the family Delta_q, q in [0,1), of the SU_q(2)-comultiplications on the C*-algebra A\cong C(SU_q(2)), we show that there exist unitary operators Omega_q such that Delta_q(x)=Om…

Quantum lens spaces and principal actions on graph C*-algebras
Wojciech Szymanski
We study certain principal actions on noncommutative C*-algebras. Our main examples are the Z_p- and T-actions on the odd-dimensional quantum spheres, yielding as fixed-point algeb…

Graph C*-algebras and Z/2Z-quotients of quantum spheres
P. M. Hajac, R. Matthes, W. Szymanski
We consider two Z/2Z-actions on the Podles generic quantum spheres. They yield, as noncommutative quotient spaces, the Klimek-Lesniewski q-disc and the quantum real projective spac…
