Results on solutions for several $$q$$-Painlevé difference equations concerning rational solutions, zeros, and poles. (English) Zbl 07290887
Summary: 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 $$f(z)$$ with zero order, their $$q$$-differences $$\Delta_q f(z)=f(q z)-f(z)$$, and divided differences $$\Delta_q f(z)/f(z)$$. 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 Y. Liu and Y. Zhang [Adv. Difference Equ. 2018, Paper No. 282, 9 p. (2018; Zbl 1446.39019)] and X. Qi and L. Yang [Electron. J. Differ. Equ. 2015, Paper No. 59, 9 p. (2015; Zbl 1314.39002)].
