摘要
推广了著名的Petrich的完全正则半群为群的正规带当且仅当它为完全单半群的强半 格的结果,证明了完全正则半群为群的正则(或右拟正规)带当且仅当它是完全单半群的HG(LG)- 强半格.
The famous result of Petrich, a completely regular semigroup is a normal cryptogroup if and only if it is a strong semilattice of completely simple semigroups is generalized, we prove that a completely regular semigroup is a regular(or right quasinormal) cryptogroup if and only if it is an HG(LG)- strong semilattice of completely simple semigroups.
