Characteristic classes of foliations via SAYD-twisted cocycles
(European Mathematical Society, 2015)
We find the first non trivial “SAYD-twisted” cyclic cocycle over the groupoid action algebra under the symmetry of the affine linear transformations of the Euclidian space. We apply the cocycle to construct a characteristic ...
A characteristic map for compact quantum groups
(Springer Heidelberg, 2017-09)
We 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 ...
Hopf-dihedral (co)homology and L-theory
(European Mathematical Soc, 2018-03-23)
We 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 ...
