A construction of normal crypto ο-superabundant semigroups
Yizhi Chen · 2010
In this paper,a new construction theorem of normal crypto ο-abundant semigroups is given,i.e.,an ο-abundant semigroup is a normal crypto ο-abundant semigroup if and only if it is a strong semilattice of completely Jο-simple semigroups.Actually,the main result in this paper is a generalization of the corresponding ones of normal crypto semigroups and normal cryptogroups in superabundant and completely regular semigroups respectively.
