幺半范畴、2-迹和循环上同调

Monoidal Categories, 2-Traces, and Cyclic Cohomology

Mohammad Hassanzadeh, Masoud Khalkhali, Ilya Shapiro

摘要:

本文证明了对有单位的结合代数对象(分别为余单位余结合余代数对象),可以在赋有对称$2$ -迹的任意交换幺幺半范畴$\mathcal{C}$上附加一个循环的(分别为.上循环)模,因此谈到(余)代数的循环(余)同调“系数在$F$中“。我们观察到,如果$\mathcal{M}$是一个$\mathcal{C}$ -双模范畴配备了一个稳定的中心对,那么$\mathcal{C}$获取对称的2-迹。并导出了对称$2$ -逆轨道和稳定中心逆轨道的对偶概念。作为应用,我们可以恢复所有的Hopf循环型(上)同调论,获得反Yetter-Drinfeld模的概念性理解,并给出循环上同调的无公式定义.机器也可以应用于设置更一般的比霍普夫代数模和余模。

英文摘要:

In this paper we show that to a unital associative algebra object (resp. co-unital co-associative co-algebra object) of any abelian monoidal category $\mathcal{C}$ endowed with a symmetric $2$-trace, one can attach a cyclic (resp. cocyclic) module, and therefore speak of the cyclic (co)homology of the (co)algebra "with coefficients in $F$". We observe that if $\mathcal{M}$ is a $\mathcal{C}$-bimodule category equipped with a stable central pair then $\mathcal{C}$ acquires a symmetric 2-trace. The dual notions of symmetric $2$-contratraces and stable central contrapairs are derived as well. As an application we can recover all Hopf cyclic type (co)homology theories, obtain a conceptual understanding of anti-Yetter-Drinfeld modules, and give a formula-free definition of cyclic cohomology. The machinery can also be applied in settings more general than Hopf algebra modules and comodules.
