In the first part of this paper, we characterize graded rings R=⊕σ∈GRσ for which the category R-gr is equivalent with a category of modules over a certain ring. In the second part, sufficient conditions are given for the following implication to hold: if R-gr is equivalent with R1-mod (1 is the unit element of G), then R is a strongly graded ring. © 1988.

Abstract
In the first part of this paper, we characterize graded rings R=⊕σ∈GRσ for which the category R-gr is equivalent with a category of modules over a certain ring. In the second part, sufficient conditions are given for the following implication to hold: if R-gr is equivalent with R1-mod (1 is the unit element of G), then R is a strongly graded ring. © 1988.File in questo prodotto:
