摘要
引进模的M-投射维数和环的M-总体维数的概念,采用比较简便的方法,得到环R的M-总体维数和环eRe的(eRRM)-总体维数之间的相等关系.
In this paper,a concept of M-projective dimensions of modules and M-global dimensions of rings was introduced. It is proved that the eR ×R M-global dimension of ring eRe is equal to the M-global R dimension of ring R by a simple easy way.
