normal homomorphism

用法例句

Minimal normal congruence of DI-C_ω-Semigroup generating by comgruence pair;

双C_ω—半群由同余对生成的最小正规同余

By defining normal congruences and normal subsemigroup,the rectangular congruence pair is constructed to investigate the rectangular group congruences on E-inversive semigroup.

研究同余是研究半群的一种最常用的方法,以下主要通过定义正规同余和正规子半群来构造矩形同余对,从而研究E-逆半群上的矩形群同余。
