摘要
本文主要研究单位球B^n到单位球B^N上全纯逆紧映射的问题.对于B^n到B^N的全纯逆紧映射映射,当其几何秩为κ_0且N=n+((2n-κ_0-1)κ_0)/2时,给出了其正规化映射的一个刻画.
The paper is concerned with the study of rational proper holomorphic maps from the unit ball B^n to the unit ball B^N.When the geometric rank of the maps are k0 and N=n+(2n-k0-1)k0/2,we give a characterization of their normalized maps.
