摘要
In the 1960s Maurice Auslander proved the following important result. Let R be the commutative polynomial ring C[x(1),..., x(n)], and let G be a finite small subgroup of GLn(C) acting on R naturally. Let A be the fixed subring R-G := {a is an element of R|g(a) = a for all g is an element of G}. Then the endomorphism ring of the right A-module RA is naturally isomorphic to the skew group algebra R*G. In this paper, a version of the Auslander theorem is proven for the following classes of noncommutative algebras:
