Ann-范畴的结构

Structure of Ann-Categories

Nguyen Tien Quang

摘要:

本文给出了一种结构变换,通过这种变换,从一个Ann范畴$\A,$得到它的$(R,M)$型的约化Ann范畴,其结构是五个函数族$k=(ξ,η,α,λ,ρ)$ .然后我们将证明每个Ann-范畴由三个不变量决定:1。环$Π_0(\A)$的对象的同构类的$\A$,2。$Π_0(\A)$ -双模$Π_1(\A) = \Aut_{\A}(0),$ 3.元素$ \bar{k}\in H^{3}_{M}(Π_0(\A), Π_1(\A))$(MacLane的环上同调)。

英文摘要:

This paper presents the structure conversion by which from an Ann-category $\A,$ we can obtain its reduced Ann-category of the type $(R,M)$ whose structure is a family of five functions $k=(ξ,η,α,λ,ρ)$. Then we will show that each Ann-category is determined by three invariants: 1. The ring $Π_0(\A)$ of the isomorphic classes of objects of $\A$, 2. $Π_0(\A)$-bimodule $Π_1(\A) = \Aut_{\A}(0),$ 3. The element $ \bar{k}\in H^{3}_{M}(Π_0(\A), Π_1(\A))$ (the ring cohomology due to MacLane).
