Quantum isometry groups of the Podles spheres

For μ∈(0,1), c⩾0, we identify the quantum group SOμ(3) as the universal object in the category of compact quantum groups acting by ‘orientation and volume preserving isometries’ in the sense of Bhowmick and Goswami (2009) [4], on the natural spectral triple on the Podles sphere constructed by Dabrowski, D'Andrea, Landi and Wagner (2007) in [9].
