THE CHARACTERIZATION OF n-REGULARMONOIDS BY FLATNESS PROPERTY |
QIAO Hu-sheng,ZHENG Qi-lian
|
Abstract: |
In this paper, we investigate the problem of generalization of principal weak flatness. Using equal systems of tensor products and the method of homological classiflcation, we obtain the characterizations of generally regular monoids, which extends the main results on the characterizations of regular monoids. |
Key words: regular monoid n-regular monoid principal weak flatness homological classiflcation |
