摘要
研究了涉及亚纯函数及其导数具有三个公共值的唯一性问题,得到的结果改进了LahiriI.,张庆彩和仪洪勋等的有关定理,并有例子表明所得结果是精确的.
In this paper, the problem of uniqueness for meromorphic functions concerning differential polynomials sharing three values with some finite weighted is studied, and the given results which extend the theorems of Lahiri I., Zhang Q C. and Yi H X.et al. Example is provided to show that the result in this paper is sharp.
