G-型分次对偶模的同调维数

Homological Dimention of Graded Duality Module

文章主要研究Gr-凝聚环中每个f.g .半自反分次模的分次对偶模的平坦维数和分次投射维数之间的关系 ,以及与分次环的gr.w .gl.dim关系 ,所得的结果包含了非分次的情形。

In this paper we discuss flat dimention and graded projective dimention of graded duality module of every f.g. graded semi-selfreflexive module in gr-coherent ring .The conclusions extend some results in no-graded statements.
