Results on Solutions for Several q-Painlevé Difference Equations concerning Rational Solutions, Zeros, and Poles

Abstract EN

In this article, we discuss the problem about the properties on solutions for several types of q-difference equations and obtain some results on the exceptional values of transcendental meromorphic solutions fz with zero order, their q-differences Δqfz=fqz−fz, and divided differences Δqfz/fz.

In addition, we also investigated the condition on the existence of rational solution for a class of q-difference equations.

Our theorems are some extensions and supplement to those results given by Liu and Zhang and Qi and Yang.
