讨论分次环R、单位元分支环Re、环R与smash积环R#G间Ki-群的关系,从而给出扩大(G,H)-分次环相关环的Ki-群的关系刻划(i=0,1)。
It discusses the relation of the Ki-groups between the graded ring, the identity branch ring Ri, ring R and smash product ring R#G, and then give the characterization of the K,-groups of rings related to the augmented (G, H) -graded ring.
