Uniqueness of meromorphic solutions of a certain type of difference equations

Jun-Fan Chen and Shu-Qing Lin

Fujian Normal University


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
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.
