摘要: GP-平坦S-系是主弱平坦S-系的推广。刻画了S-系的GP-平坦性在直积下封闭的幺半群的特征, 将自然数为1的主弱凝聚幺半群结果推广到任意存在的自然数的情形。

关键词: 直积, GP-左凝聚幺半群, GP-平坦

Abstract: GP-flat S-act is a genetalization of principally weakly flat S-act. Monoids over which GP-flatness property of S-acts is preserved under direct product are characterized, and some known results of the case n=1 according to principally weakly coherent monoids to any other natural numbers is extended.

Key words: direct product, GP-left coherent monoid, GP-flat
