关于幺半群的剩余紧性、Schutzenberger群及其相关作用

On Residual Finiteness of Monoids, their Schutzenberger Groups and Associated Actions

Robert Gray, Nik Ruskuc

摘要:

本文讨论了以下性质之间的联系:幺半群M的剩余有限性(RFM); M的Schutzenberger群的剩余有限性(RFSG); M在其Green R-类和Green L-类上的自然作用的剩余有限性(RFRL)。一般的问题是(RFM)是否意味着(RFSG)和/或(RFRL),反之亦然。我们在下列情形的所有可能组合中考虑这些问题:M是任意幺半群; M是任意正则幺半群; M的每个J-类都有N个R-类和N个L-类; M有N个左理想和N个右理想。在每一种情况下,我们都得到了完整的答案。

英文摘要:

In this paper we discuss connections between the following properties: (RFM) residual finiteness of a monoid M; (RFSG) residual finiteness of Schutzenberger groups of M; and (RFRL) residual finiteness of the natural actions of M on its Green's R- and L-classes. The general question is whether (RFM) implies (RFSG) and/or (RFRL), and vice versa. We consider these questions in all the possible combinations of the following situations: M is an arbitrary monoid; M is an arbitrary regular monoid; every J-class of M has finitely many R- and L-classes; M has finitely many left and right ideals. In each case we obtain complete answers.
