本文主要利用差分的Nevanlinna理论,研究了几种不同类型的复差分微分多项式的零点情况,推广了微分多项式理论中的一些经典结果,同时也推广了部分差分多项式的结果.另外,本文还得到了某些差分微分方程解的存在性.
In this paper, using the difference Nevanlinna theory, we mainly investigate the zeros of difference-differential polynomials of different types, and extend some results in differential polynomials or difference polynomials. Furthermore, we obtain some existence about the solutions of difference-differential equations.
