关于局部左正则密码群并半群的等价表述

Equivalence Formulation of Local Left Regular Cryptogroup and Semigroup

在对局部左正则密码群并半群的若干研究中,给出了两个关于偏序关系的等价刻画,证明了完全正则半群S是一个局部左正则密码群并半群当且仅当H1=≤或H2=≤.

In research on local left regular cryptogroups and semigroup, two equivalence formula on partial order relation are given. It is proved that a completely regular semigroup S is a local left regular cryptogroup and semigroup if H1≤orH2=≤.
