摘要:

通过研究双随机矩阵半群Dn 中的完全正则元,进而获得了Dn 中的完全正则半群的结构,即(CR)n ={PE|P ∈ ∩E ∈Bn
GE,E ∈Bn ⊆E(Dn)} 是完全正则半群当且仅当Bn是半格。

关键词: 正则元, 完全正则元, 幂等元, 置换阵

Abstract:

This paper achieves the structure of completely regular semigroup through the investigation of completely regular elements
in doubly-stochastic matrix semigroup Dn. Namely,(CR)n ={PE|P ∈ ∩E ∈BnGE,E ∈Bn ⊆E(Dn)} is completely regular semigroup if and only
if Bn is a semi-lattice.

Key words: regular, completely regular element, idempotent, permutation matrix
