Brandt半群的正规子半群与自同态

The Normal Subsemigroups and Endomorphisms of Brandt Semigroups

该文从Brandt半群B=B(G,I)的真同余出发,研究了B(G,I)的正规子半群与自同态,进而刻划出Brandt半群上所有的正规子半群与所有的自同态.

With the proper congruence of Brandt semigroups B= B（G, I）, the paper researches on the normal subsemigroups and endomorphisms of B（G, I）, and describes all normal subsemigroups and endomorphisms of Brandt semigroups B（G,I）.
