Chern character, Hopf algebras, and BRS cohomology
Denis Perrot
We present the construction of a Chern character in cyclic cohomology, involving an arbitrary number of associative algebras in contravariant or covariant position. This is a gener…
Retraction of the bivariant Chern character
Denis Perrot
We show that the bivariant Chern character in entire cyclic cohomology constructed in a previous paper in terms of superconnections and heat kernel regularization, retracts on peri…
BRS-Chern-Simons forms and cyclic homology
Denis Perrot
We use some BRS techniques to construct Chern-Simons forms generalizing the Chern character of K_1 groups in the Cuntz-Quillen description of cyclic homology.
BRS Cohomology And The Chern Character In Non-Commutative Geometry
Denis PERROT
We establish a general local formula computing the topological anomaly of gauge theories in the framework of non-commutative geometry.
