T-半群

T-semigroups

定义了T 半群 ,并刻划了T 半群的某些性质 .证明了T 半群是t 半群 ,但t 半群未必是T 半群 ;正则半群是t 半群 ,但未必是T 半群 ;T 半群的同态像仍是T

After introduced the notion of T-semigroup,some properties of it are discussed.It is showed that T-semigroup is t-semigroup,but the reverse in not true;the regular semigroup is t-semigroup,however,it is not always T-semigroup;T-semigroups are presevered by homomorphic images.
