摘要
引入了Γ 左零半群和Γ 左群的概念。讨论了Γ 左群的一些性质。利用Γ 群 ,给出了Γ 左群的分解 ,证明了Γ 半群M是Γ 左群当且仅当M是Γ 群的Γ
The concepts of Γ-left zero semigroups and Γ-left group some properties of Γ-left groups are discussed and are introduced. Finally we give a decomposition theorem for Γ-left group is given in terms of Γ-groups. It is roved that a semigroup M is a Γ-left group if and only if M is a Γ-left zero band of Γ-groups.
