Uniqueness of meromorphic solutions of a certain type of difference equations

Abstract

In this paper, we study the uniqueness of two finite order transcendental meromorphic solutions $f(z)$ and $g(z)$ of the following complex difference equation
$$A_{1}(z)f(z+1)+A_{0}(z)f(z)=F(z)e^{\alpha(z)}$$
when they share 0, $\infty$ CM, where $A_{1}(z),$ $A_{0}(z),$ $F(z)$ are non-zero polynomials, $\alpha(z)$ is a polynomial.
Our result generalizes and complements some known results
given recently by Cui and Chen, Li and Chen. Examples for the precision of our
result are also supplied.
