Turán type inequalities for oscillatory special functions
Ibrahim Aktaş, Árpád Baricz
In this paper our aim is to prove a conjecture of Á. Baricz on Bessel functions of the first kind, which improves the classical Turán type inequality for Bessel functions of the fi…
On partial sums of normalized q-Bessel functions
Halit Orhan, İbrahim Aktaş
In the present investigation our main aim is to give lower bounds for the ratio of some normalized -Bessel functions and their sequences of partial sums. Especially, we consider…
Bounds for radii of starlikeness of some -Bessel functions
İbrahim Aktaş, Árpád Baricz
In this paper the radii of starlikeness of the Jackson and Hahn-Exton -Bessel functions are considered and for each of them three different normalization are applied. By applyin…
Bounds for radii of starlikeness and convexity of some special functions
İbrahim Aktaş, Árpád Baricz, Halit Orhan
In this paper we consider some normalized Bessel, Struve and Lommel functions of the first kind, and by using the Euler-Rayleigh inequalities for the first positive zeros of combin…
Bounds for the radii of univalence of some special functions
Ibrahim Aktaş, Árpád Baricz, Nihat Yağmur
Tight lower and upper bounds for the radius of univalence of some normalized Bessel, Struve and Lommel functions of the first kind are obtained via Euler-Rayleigh inequalities. It…
