A
Unicity Theorem for Meromorphic Functions
Huiling Qiu and Mingliang
Fang
Abstract.
In this paper, we study the uniqueness of meromorphic
functions and prove the following result: Let 
be a positive |
integer,
 ,
and let 
and 
be two nonconstant meromorphic functions whose poles are
of multiplicities at |
least
2. If  ,
 ,
and  ,
then  .
This result also answer a question |
of
Gross [4] and
improve some results
of Fang and Xu [1], Yi [14] and Yi [15].
