不可分解作用的乘积不可分解的幺半群
Monoids over which products of indecomposable acts are indecomposable
摘要:
本文证明了对幺半群$S$,不可分解右$S$ -系的积是不可分解的当且仅当$S$包含右零点.此外,还证明了不可分解右$S$ -系的子系是不可分解的当且仅当$S$是左可逆的.最后,我们证明了右$S$ -act $Θ_S$是乘积平坦的当且仅当$S$包含一个左零.
英文摘要:
In this paper we prove that for a monoid $S$, products of indecomposable right $S$-acts are indecomposable if and only if $S$ contains a right zero. Besides, we prove that subacts of indecomposable right $S$-acts are indecomposable if and only if $S$ is left reversible. Ultimately, we prove that the one element right $S$-act $Θ_S$ is product flat if and only if $S$ contains a left zero.
