利用亚纯函数的Nevanlinna值分布理论,讨论了复一般差分方程解的存在性问题,推广和改进了一些文献的结果.同时,也讨论了一类复差分方程组亚纯解的存在性.
By using the Nevanlinna value distribution theory of meromorphic functions, some results are improved and generalized. At the same time, the existence of meromorphic solutions of a type of systems of complex difference equations is also investigated.
