Abstract
In this paper, using the theory of linear algebra, we investigate the non-linear difference equation of the following form in the complex plane:
where n, s are the positive integers, \(p(z)\not \equiv 0\) is a polynomial and \(\eta , \beta _1, \ldots , \beta _s, \alpha _1, \ldots , \alpha _s\) are the constants with \(\beta _1 \ldots \beta _s\alpha _1 \ldots \alpha _s\ne 0\), and show that this equation just has meromorphic solutions with hyper-order at least one when \(n\ge 2+s\). Other cases are also obtained.
