摘要:

设X为有限集合, E为X上的等价关系, 令OIE*(X)为所有E类保序严格部分一一变换所构成的半群. 在一定条件下讨论OIE*(X)的极大逆子半群.

关键词: 保E*关系, 保序, 极大逆子半群

Abstract:

Let E be an equivalence on a finite set X, and OIE*(X) be the semigroup consisting of all orderpreserving strictly partial oneone transformations of type E, then we  characterized the maximal inverse subsemigroup of OIE*(X) under certain assumptions.

Key words: E*preserving, preserving order, maximal invese subsemigruops
