Normal ■~#-Abundant Semigroups
Xiangzhi Kong · Journal of Southwest China Normal University · 2008
The usual Green relations,*-Green relations are generalized to #-Green relations and the semilattice decomposition of■#-abundant semigroups is given.By using this decomposition,the authors show that an■#-abundant semigroup is a normal■#-abundant semigroup if and only if it is strong sem- ilattice of completely■#-simple semigroups.
