A Method of Relationship,Poly mapping and Equivalence Partition(Ⅱ)

通过对射影几何中齐次坐标的建立、数系理论中数系的扩张问题和复变函数中多值函数的多值支等有关问题讨论 ,从多值映射的角度进一步对关系、多值映射。

From the angle of multi valued mapping,the method of relationship,poly mapping and equivalence partition is further discussed through the establishment of homogeneous coordinates in projective geometry, the discussion on the dilatation of number system in the theory of numbers system and the multi valued function in complex function.
