Characteristic classes of foliations via SAYD-twisted cocycles
Rangipour, Bahram; Sütlü, Serkan Selçuk (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 ... -
Hopf-cyclic cohomology of the Connes-Moscovici Hopf algebras with infinite dimensional coefficients
Rangipour, Bahram; Sütlü, Serkan Selçuk; Aliabadi, F. Yazdani (Springer Heidelberg, 2018-12-01)We discuss a new strategy for the computation of the Hopf-cyclic cohomology of the Connes-Moscovici Hopf algebra Hn. More precisely, we introduce a multiplicative structure on the Hopf-cyclic complex of Hn, and we show ... -
Topological Hopf algebras and their Hopf-cyclic cohomology
Rangipour, Bahram; Sütlü, Serkan Selçuk (Taylor and Francis, 2019-01-29)A natural extension of the Hopf-cyclic cohomology, with coefficients, is introduced to encompass topological Hopf algebras. The topological theory allows to work with infinite dimensional Lie algebras. Furthermore, the ...
