Equivariant Chern classes in Hopf cyclic cohomology
Henri Moscovici
We present a geometric approach, in the spirit of the Chern-Weil theory, for constructing cocycles representing the classes of the Hopf cyclic cohomology of the Hopf algebra H(n) r…

Geometric construction of Hopf cyclic characteristic classes
Henri Moscovici
In earlier joint work with A. Connes on transverse index theory on foliations, cyclic cohomology adapted to Hopf algebras has emerged as a decisive tool in deciphering the total in…
