基于循环模的Hopf循环上同调的上积

Cup products in Hopf cyclic cohomology via cyclic modules I

Bahram Rangipour

摘要:

这是第一个在一系列的两个文件上继续我们的研究上积在Hopf循环上同调。本文利用代数和余代数的Hopf循环上圈构造了代数的循环上圈。在接下来的文章中,我们考虑从“等变”的Hopf循环上圈产生Hopf循环上圈。我们在这两种情况下的方法都是基于(co)循环模和双(co)循环模以及Eilenberg-Zilber定理,这与DG代数和余代数上通过迹和余迹定义的上积杯积的旧定义不同.

英文摘要:

This is the first one in a series of two papers on the continuation of our study in cup products in Hopf cyclic cohomology. In this note we construct cyclic cocycles of algebras out of Hopf cyclic cocycles of algebras and coalgebras. In the next paper we consider producing Hopf cyclic cocycle from "equivariant" Hopf cyclic cocycles. Our approach in both situations is based on (co)cyclic modules and bi(co)cyclic modules together with Eilenberg-Zilber theorem which is different from the old definition of cup products defined via traces and cotraces on DG algebras and coalgebras.
