摘要
In this article, we consider a partial action alpha of a finite group G on a ring R which possesses an enveloping action. Properties of the fixed subring R-alpha are studied. Among other results, under some assumptions, we describe the prime radical, the Jacobson radical, and the upper nil radical. We also study semisimplicity, von Newmann regularity, and Goldie conditions.
