Radius of Uniform Convexity of some special functions
İbrahim Aktaş, Evrim Toklu, Halit Orhan
In this investigation our main aim is to determine the radius of uniform convexity of the some normalized q-Bessel and Wright functions. Here we consider six different normalized f…
Second Hankel determinant for certain subclasses of bi-univalent functions involving Chebyshev polynomials
Halit Orhan, Evrim Toklu, Ekrem Kadıoğlu
In this paper our purpose is to find upper bound estimate for the second Hankel determinant for functions defined by convolution belonging to the class $\m…
Second Hankel Determinant for certain class of bi-univalent functions defined by Chebyshev polynomials
H. Orhan, N. Magesh, V. K. Balaji
Making use of Chebyshev polynomials, we obtain upper bound estimate for the second Hankel determinant of a subclass of bi-univalent function c…
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 convexity of some -Bessel functions
Halit Orhan, İbrahim Aktaş
In the present investigation, by applying two different normalizations of the Jackson and Hahn-Exton -Bessel functions tight lower and upper bounds for the radii of convexity of…
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…
