The Relation P and Q on the Congruence Lattice of Two Types of Bisimple ω-Semigroups
Zhong Chen · Journal of Jiangxi Normal University · 2007
The paper studies the relation between congruence lattice and green,s relation on bisimple ω-semigroup.We prove that: the relations P and Q are congruences on C(S) and P∩Q=eC(S),ρ=ρP∨ρQ=ρP∧ρQ in two kinds of bisimple ω-semigroup.
