我们考虑零是全部功能的差别产品的衍生物的差别微分的多项式的分布。我们也调查分享普通的值的全部函数的差别微分的多项式的唯一问题。
We consider the zeros distributions of difference-differential polynomials which are the derivatives of difference products of entire functions. We also investigate the uniqueness problems of difference-differential polynomials of entire functions sharing a common value.
