Abstract

In the present investigation our main aim is to give lower bounds for the ratio of some normalized $q$-Bessel functions and their sequences of partial sums. Especially, we consider Jackson's second and third $q$-Bessel functions and we apply one normalization for each of them.

Keywords: analytic function, $q$-Bessel functions, univalent functions, partial sums
