摘要
研究了强极大平坦模的性质和环的左整体强极大平坦维数,得到环的强极大平坦维数不超过正整数n;利用环的左整体强极大平坦维数给出了环的左整体维数的一个上界估计.
Some properties of strongly flat modules and left global strongly flat dimension of the ring are investigated. It is obtained that the left global strongly flat dimension of a ring does not exceed non- negative integers n, and an upper bound of the left global dimension of the ring is give by using the left global strongly flat dimension of the ring.
