关于差分多项式零点分布和导数唯一性的若干结果

Some results on zeros distributions and uniqueness of derivatives of difference polynomials

Kai Liu, Xin-Ling Liu, Ting-Bin Cao

摘要:

研究了亚纯函数差分多项式导数的零点分布,给出了一些结果,这些结果可以看作是Hayman猜想\cite{hayman1}的离散类似,也部分回答了\cite [P448]{luolin}中的问题.我们还研究了整函数的差分微分多项式具有一个公共值的唯一性问题。这些定理改进了Luo和Lin的\cite{luolin}的结果以及作者\cite{liuliucao}的一些结果.

英文摘要:

We consider the zeros distributions on the derivatives of difference polynomials of meromorphic functions, and present some results which can be seen as the discrete analogues of Hayman conjecture \cite{hayman1}, also partly answer the question given in \cite[P448]{luolin}. We also investigate the uniqueness problems of difference-differential polynomials of entire functions sharing one common value. These theorems improve the results of Luo and Lin\cite{luolin} and some results of present authors \cite{liuliucao}.
