该文研究了复平面上的亚纯函数在角域内分担两个集合的唯一性,将仪洪勋和林伟川最近得到的复平面上的亚纯函数在全平面上分担两个集合的唯一性定理中的在全平面上分担两个集合的条件改成在角域内分担两个集合,得到了几个唯一性定理.
In this paper,we first investigate the uniqueness of meromorphic functions dealing with two shared sets in an angular domain and obtain several uniqueness theorems,which extend the recent results by Yi H X and Lin W C who investigated the uniqueness of meromorphic functions dealing with two shared sets in the whole complex plane.
