Gr-凝聚环上分次W^n-模的自反性

Gr-reflexivity of Graded W^n-modules Over Gr-coherent Rings

引进了分次 wn -模 ,讨论了具有有限分次 FP-自内射维数的 gr凝聚环和分次 wn -模的自反性 .所得的结果推广了 Stentr m,Bass和黄兆泳等人的若干结果 .

We introduce graded w n-modules, describe graded FP-selfinjective dimension over Gr-coherent rings and Gr-reflexivity of graded w n-modules. The obtained results generalize the works of stentrom, Bass and Huang Zhaoyong.
