In this paper,Author had discussed Gorenstein projective dimension and injective dimension of modules on Morita equivalence rings,the results as follow:If rings R≈S,then GpdRM=GpdSF(M),GidRM=GidSF(M).
在Morita等价的环上对模的Gorenstein投射维数与内射维数进行了讨论,有如下结论:若环R≈S,则GpdRM=GpdSF(M),GidRM=GidSF(M)。
Similar to the injective resolution of M,the essential injective resolution and left essential injective dimension of M are defined,and the connections between left injecti.
在M-内射模的基础上引进了M-本质内射模的概念,研讨了M-本质内射模的一些性质,并且引入了M的本质内射分解和本质内射维数的概念,深入探讨了内射维数和本质内射维数之间的关系,得出了一些重要的结论。
