Topological Hopf algebras and their Hopf-cyclic cohomology
Bahram Rangipour, Serkan Sütlü
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 dime…
Hopf algebra and universal Chern classes
Henri Moscovici, Bahram Rangipour
We construct a variant of the Hopf algebra , which acts directly on the noncommutative model for the generic space of leaves rather than on its frame…
Generalized Coefficients for Hopf Cyclic Cohomology
Mohammad Hassanzadeh, Dan Kucerovsky, Bahram Rangipour
A category of coefficients for Hopf cyclic cohomology is defined. It is shown that this category has two proper subcategories of which the smallest one is the known category of sta…
Characteristic classes of foliations via SAYD-twisted cocycles
Bahram Rangipour, Serkan Sutlu
We have previously shown that the truncated Weil algebra of any Lie algebra is a Hopf-cyclic type complex with nontrivial coefficients. In this paper we apply this result to transf…
SAYD modules over Lie-Hopf algebras
B. Rangipour, S. Sutlu
In this paper a general van Est type isomorphism is established. The isomorphism is between the Lie algebra cohomology of a bicrossed sum Lie algebra and the Hopf cyclic cohomology…
Lie-Hopf algebras and their Hopf cyclic cohomology
Bahram Rangipour, Serkan Sutlu
The correspondence between Lie algebras, Lie groups, and algebraic groups, on one side and commutative Hopf algebras on the other side are known for a long time by works of Hochsch…
