Skew Group Rings which are Semi-Hereditary Orders and Prüfer Orders in Simple Artinian Rings
by Marubayashi, Hidetoshi; Yi, Zhong
Let R be a commutative ring, let G be a finite group acting on R as automorphisms of R and let R * G be the skew group ring. By using the decomposition subgroups of G, the inertial subgroups of G, the properties of the coefficient ring R and the properties of the fixed subring R
G
, some necessary and sufficient conditions for R * G to be a prime Goldie ring, a semi-hereditary order in a simple Artinian ring, or a Prüfer order in a simple Artinian ring are given.
