I_(E_(2))上局部保距变换半群PDI_(E_(2))的Green关系

Green's Relations of the Partial-preserving Partial Transformation Semi-group PDI_(E_(2)) on I_(E_(2))

定义了既保等价关系E,又在E类上保距的部分双射半群PDIE,并给出了PDI_(E)上的局部保距变换半群I_(E_(2))的Green关系.

In this paper,we define a partial-preserving partial transformation semi-group PDI_(E) which preserves an equivalence relation E and distance based on E-classes,subsequently,we dis⁃cuss Green's relations in the context of the partial-preserving partial transformation semi-groupPDI_(E_(2)).
