The properties of the meromorphic solutions of some difference equations

In this article, we treat complex difference equation of the form A(n)(z)f (z)+n+ center dot center dot center dot +A(1)(z)f (z) A(0)(z)f (z) = A(n+1)(z), where A(j)(z)(j=0,1,...,n,n+1) are meromorphic functions. We give answers to the growth estimates of the meromorphic solutions, and firstly consider the deficiency and fixed points of the meromorphic solutions of these equations. Some examples are listed to show that the result about the properties of fixed points is the best possible in a certain sense.
