Yayın A characteristic map for compact quantum groups(Springer Heidelberg, 2017-09) Kaygun, Atabey; Sütlü, Serkan SelçukWe show that if G is a compact Lie group and g is its Lie algebra, then there is a map from the Hopf-cyclic cohomology of the quantum enveloping algebra U-q(g) to the twisted cyclic cohomology of quantum group algebra O(G(q)). We also show that the Schmudgen-Wagner index cocycle associated with the volume form of the differential calculus on the standard Podles sphere O(S-q(2)) is in the image of this map.Yayın Hopf-dihedral (co)homology and L-theory(European Mathematical Soc, 2018-03-23) Kaygun, Atabey; Sütlü, Serkan SelçukWe develop an appropriate dihedral extension of the Connes-Moscovici characteristic map for Hopf *-algebras. We then observe that one can use this extension together with the dihedral Chern character to detect non-trivial L-theory classes of a *-algebra that carry a Hopf symmetry over a Hopf *-algebra. Using our machinery we detect a previously unknown L-class of the standard Podles sphere.
