On some geometric properties and Hardy class of q-Bessel functions

Department of Mathematics, Kamil Özdağ Science Faculty, Karamanoğlu Mehmetbey University, Yunus Emre Campus, 70100, Karaman-Turkey

In this paper, we deal with some geometric properties including starlikeness and convexity of order α of Jackson’s second and third q-Bessel functions which are natural extensions of classical Bessel function Jν. In additon, we determine some conditions on the parameters such that Jackson’s second and third q-Bessel functions belong to the Hardy space and to the class of bounded analytic functions.
