Let f and g be two nonconstant meromorphic functions. Shared value problems related to f and g are investigated in this paper. We give sufficient conditions in terms of weighted value sharing which imply that f is a linear transformation or inversion transformation of g. We also investigate the uniqueness problem of meromorphic functions with their difference operators and derivatives sharing some values.

亚纯函数关于其差分算子和导数的唯一性

fg为两个非恒定亚纯函数。本文研究了与fg有关的共享价值问题。我们在加权值共享方面给出了充分的条件,这意味着fg的线性变换或求逆变换 。我们还研究了亚纯函数的差分算子和导数共享一些值的唯一性问题。
