Graph D-saturated properties of semigroups
摘要
The aim of this paper is to study (power; divisibility) annihilator D-saturated semigroups. We obtain necessary and sufficient conditions for an IC abundant semigroup (a superabundant semigroup; a completely 0-simple semigroup) to be power D-saturated. It is determined when a superabundant semigroup (a primitive abundant semigroup) is annihilator D-saturated. Also, we describe the structure of divisibility D-saturated semigroups.
