The cyclic homology of crossed product algebras.

Abstract

If M is a module over a commutative ring Λ, we will denote by M (k) the iterated tensor product, defined by M (0) = A and M (k + 1} = M (k} ® M. If M and N are graded modules, we will denote by M ® 7V their graded tensor product.We would like to thank J. Block, J.-L. Brylinski and C. Kassel for a number of interesting discussions on the results presented here.
