Zeros and fixed-points onmeromorphic solutions of a certain type of first order difference equation

摘要

This paper is devoted to studying fixed points of meromorphic solutions f (z) for certain difference equations of first order. A number of results are obtained concerning zeros and fixed points of f (z) and its shifts f (z +n), difference △ f (z) = f (z +1)? f (z) and divided differences △ f (z)/f (z) .
