摘要
本文研究了半群半直积的主投影性质.利用适当半群,获得了右主投影半群半直积的充分和必要条件,推广了半直积的一些结果.
In this article, we investigate the principal projective properties of semidirect products of monoids. By the adequate semigroup, we obtain the necessary and sufficient condition for semidirect products of monoids to be right principal projective property of monoid. Our known results strengthen and enrich the results on semidirect products.
