Commutative graded-$n$-coherent and graded valuation rings

Let $R= \oplus_{ \alpha \in G} R_{\alpha}$ be a commutative ring with unity graded by an arbitrary grading commutative monoid $G$. For each positive integer, the notions of a graded-n-coherent module and a graded-n-coherent ring are introduced. In this paper many results are generalized from $n$-coherent rings to graded-$n$-coherent rings. In the last section, we provide necessary and sufficient conditions for the graded trivial extension ring to be a graded-valuation ring.

Keywords:

coherent rings and modules, n-coherent rings and modules graded modules and rings, graded-coherent rings and modules, graded-valuation rings, graded trivial extension ring,
