摘　　要：引入了强LR-π-逆半群的概念,讨论了2个半群的半直积和圈积,分别给出了2个半群的半直积和圈积是强LR-π-逆半群的充分必要条件.We introduce the concept of strong left and right 7r-regular semigroups, and discuss the semidirect prod- uct and wreath product of two semigroups. We obtain the necessary and sufficient conditions for both the semidirect product and wreath product of two semigroups to be strong LR-π-inverse semigroups, respectively.

关 键 词：强LR-π-逆半群 半直积 圈积
