摘要
研究了条件(P)的推广形式——条件(PT)及其对幺半群的刻画.证明了所有挠自由右S-系满足条件(PT)当且仅当S是左几乎正则幺半群;所有右S-系满足条件(PT)当且仅当S是正则幺半群.
The condition (P\-T) which is a generalization of condition (P) and its relation with monoid are studied. It is Proved that all torsion free right S\|acts satisfy condition (P\-T) if and only if S is a left, Almost regular monoid, and that all right S\|acts satisfy condition (P\-T) if and only if S is a regular monoid.
