On second cohomology of duals of compact quantum groups
(World Scientific Publishing, 2011-09)We show that for any compact connected group G the second cohomology group de ned by unitary invariant 2-cocycles on ^G is canonically isomorphic to H2(\Z(G); T). This implies that the group of autoequivalences of the C ...
