摘要

摘要本文的目的是描述几个Fermat型偏微分差分方程组解对的性质。我们的定理展示了这些系统的有限阶超越整体解的形式，这是对徐、曹、刘等先前定理的一些扩展和改进。此外，我们给出了一系列例子，证明了这些系统有限阶超越整个解的存在条件和形式是精确的。

The study of solutions for several systems of PDDEs with two complex variables

Abstract The purpose of this article is to describe the properties of the pair of solutions of several systems of Fermat-type partial differential difference equations. Our theorems exhibit the forms of finite order transcendental entire solutions for these systems, which are some extensions and improvement of the previous theorems given by Xu, Cao, Liu, etc. Furthermore, we give a series of examples to show that the existence conditions and the forms of transcendental entire solutions with finite order of such systems are precise.
