Para-Hopf algebroids and their cyclic cohomology | | M. Khalkhali

11 May 2001 | | Subject: | K-Theory and Homology | math.KT | | Abstract: | We introduce the concept of {it para-Hopf algebroid} and define their cyclic cohomology in the spirit of Connes-Moscovici cyclic cohomology for Hopf algebras. Para-Hopf algebroids are closely related to, but different from, Hopf algebroids. Their definition is motivated by attempting to define a cyclic cohomology theory for Hopf algebroids in general. We show that many of Hopf algebraic structures, including the Connes-Moscovici algebra $mathcal{H}_{FM}$, are para-Hopf algebroids. | | Source: | arXiv, math.KT/0105105 | | Services: | Forum | Review | PDF | Favorites | |
