Some new inequalities for the $q$-gamma and related functions

Number Theory 2019-02-26 v2

Abstract

We consider convexity and monotonicity properties for some functions related to the qq-gamma function. As applications, we give a variety of inequalities for the qq-gamma function, the qq-digamma function ψq(x)\psi_q(x), and the qq-series. Among other consequences, we improve a result of Azler~and~Grinshpan about the zeros of the function ψq(x)\psi_q(x). We use qq-analogues for the Gauss multiplication formula to put in closed form members of some of our inequalities.
