Quantum Isometry groups of the Podles Spheres
arXiv:0810.0658
Abstract
For we identify the quantum group as the universal object in the category of compact quantum groups acting by `orientation and volume preserving isometries' in the sense of \cite{goswami2} on the natural spectral triple on the Podles sphere constructed by Dabrowski, D'Andrea, Landi and Wagner in \cite{Dabrowski_et_al}.
Some explanations added in subsections 3.3 and 3.4, to appear in J.Funct.Anal
