Brief Description:
Special Note:
Abstract:
We will show how to define the cyclic differential and cyclic homology of an associative algebra $A$ in a more categorical manner, without using explicit resolutions such as a bar-resolution. We will also explain how the construction is related to the notion of the Drinfeld double of a tensor category.Date: Tuesday, April 18, 2006
