Alexandre Baraviera, Wagner Cortes, Marlon Soares

摘要:

本文考虑群$G$在环$R$上的扭部分作用$α$,它是伴随的部分交叉积$R*_α^wG$ .我们研究了$R*_α^wG$的交换性和简单性充要条件。设$R=C(X)$是复数上拓扑空间$X$的连续函数代数,$C(X)*_αG$是部分斜群环,其中$α$是拓扑群$G$在$C(X)$上的部分作用.本文研究了代数$C(X)$的一些拓扑性质,得到了一些结果.利用拓扑性质研究了$C(X)*_αG$的简单性,得到了$R*_α^wG$的部分交叉积的简单性结果.

英文摘要:

In this article, we consider a twisted partial action $α$ of a group $G$ on a ring $R$ and it is associated partial crossed product $R*_α^wG$. We study necessary and sufficient conditions for the commutativity and simplicity of $R*_α^wG$. Let $R=C(X)$ the algebra of continuous functions of a topological space $X$ on the complex numbers and $C(X)*_αG$ the partial skew group ring, where $α$ is a partial action of a topological group $G$ on $C(X)$. We study some topological properties to obtain results on the algebra $C(X)$. Also, we study the simplicity of $C(X)*_αG$ using topological properties and the results about the simplicity of partial crossed product obtained for $R*_α^wG$.
