具有亏值的亚纯函数的唯一性定理

On the Unicity Theorem of Meromoaphic Functions with Deficient Values

本文主要就具有某些特殊亏值关系的亚纯函数及其ｎ阶导数具有公共值的唯一性得到了一个一般性定理，改进并推广了许多先前已知的结果。

In this paper,mainly a general theorem concerning the unicity of meromorphicfunctions satisfying certain deficient relation and their n-th derivatives sharing two values isobtained.As an immediate consequence, a number of known results can be derived from thetheorem.
