摘要 通过刻画逆适当半群的一些性质,给出了一个富足半群是逆适当半群的充要条件是对于正则元a,b ∈S,a的预逆与b的预逆的积是ba的预逆.同时,给出了逆适当半群的自然偏序的性质. Through describing some properties of inverse adequate semigroups, the paper gives the sufficient and necessary conditions for an abundant semigroup to be an inverse semigroup: a,b∈S for regular element and the product of pre inverse of a and the pre inverse of b being the pre inverse ofba. Also, the paper shows the natural partial order of inverse adequate semigroups.
