| Abstract: |
| We consider the properties of completely 0-simple semigroup S when the sandwich matrix P and G are Abelian， and generalize the corresponding results for completely simple semigroups.The elements of S are characterized if the subband of S is a left zero band or a right zero band. And then we characterize the inverses of idempotents of S. |
| Key words: completely 0-simple semigroup completely simple semigroup sandwich matrix |
