连通分次与基本群

Connected gradings and fundamental group

Claude Cibils, Maria Julia Redondo, Andrea Solotar

摘要:

本文的主要目的是给出几个代数的基本群的显式计算。为此,给定一个$k$ -代数$A$,我们考虑了$A$的所有连通群$G$的分次范畴,并研究了分次与Galois覆盖的关系.该理论工具提供了有关$A$的基本群的信息,允许使用完整的分级列表进行计算。

英文摘要:

The main purpose of this paper is to provide explicit computations of the fundamental group of several algebras. For this purpose, given a $k$-algebra $A$, we consider the category of all connected gradings of $A$ by a group $G$ and we study the relation between gradings and Galois coverings. This theoretical tool gives information about the fundamental group of $A$, which allows its computation using complete lists of gradings.
