摘要
本文研究了主弱平坦性质的推广问题.利用张量积相等的等式组,以及同调分类方法,获得了对广义正则的幺半群的刻画结果,推广了关于正则幺半群刻画的主要的结果.
In this paper, we investigate the problem of generalization of principal weak flatness. Using equal systems of tensor products and the method of homological classification, we obtain the characterizations of generally regular monoids, which extends the main results on the characterizations of regular monoids.
