In this paper, we investigate the growth of meromorphic solutions of homogeneous and non-homogeneous linear difference equations

$$\begin{aligned} A_{k}(z)f(z+c_{k})+\cdots +A_{1}(z)f(z+c_{1})+A_{0}(z)f(z)= & {} 0, \\ A_{k}(z)f(z+c_{k})+\cdots +A_{1}(z)f(z+c_{1})+A_{0}(z)f(z)= & {} F, \end{aligned}$$

where \(A_{k}\left( z\right) ,\ldots ,A_{0}\left( z\right) ,\) \(F\left( z\right) \) are meromorphic functions and \(c_{j}\) \(\left( 1,\ldots ,k\right) \) are non-zero distinct complex numbers. Under some conditions on the coefficients, we extend early results due to Zhou and Zheng, Belaïdi and Benkarouba.

高阶线性差分方程亚纯解增长性质的研究

在本文中,我们研究了齐次和非齐次线性差分方程的亚纯解的增长

$$ \ begin {aligned} A_ {k}(z)f(z + c_ {k})+ \ cdots + A_ {1}(z)f(z + c_ {1})+ A_ {0}(z )f(z)=&{} 0,\\ A_ {k}(z)f(z + c_ {k})+ \ cdots + A_ {1}(z)f(z + c_ {1})+ A_ {0}(z)f(z)=和{} F,\ end {aligned} $$

其中\(A_ {k} \ left(z \ right),\ ldots,A_ {0} \ left(z \ right),\) \(F \ left(z \ right)\)是亚纯函数并且\( c_ {j} \) \(\ left(1,\ ldots,k \ right)\)是非零的不同复数。在系数的某些条件下,由于Zhou和Zheng,Belaïdi和Benkarouba,我们扩展了早期结果。
