Abstract
Let G be a group with identity e and R a G-graded commutative ring with 1\neq 0. In this paper we introduce the
concept of the graded (m,n)-closed ideals and graded weakly (m,n)-closed ideals. A graded proper ideal I of R is called a graded (m,n)-closed (resp. graded weakly (m,n)-closed) ideal if whenever a^m \in I (resp., 0\neq a^m \in I) for a \in h(R), then a^n \in I. Many results are given, in particular we investigate the graded (weakly) (m,n)-closed ideals in the direct product R_1 \times R_2 of G-graded rings R_1,\ R_2 and in the trivial extension R(+)M of a G-graded ring R by a graded R-module M.
