Abstract
Let R be a commutative graded ring with unity, S be a multiplicative subset of homogeneous elements of R and P be a graded ideal of R such that P?S= null . In this article, we introduce the concept of graded S-primary ideals which is a generalization of graded primary ideals. We say that P is a graded S-primary ideal of R if there exists s & ISIN;S such that for all x,y & ISIN;h(R), if xy & ISIN;P, then sx & ISIN;P or sy & ISIN;Grad(P) (the graded radical of P). We investigate some basic properties of graded S-primary ideals.
