Geometric Properties of Bessel function derivatives
Erhan Deniz, Sercan Topkaya, Murat Çağlar
In this paper our aim is to find the radii of starlikeness and convexity of Bessel function derivatives for three different kind of normalization. The key tools in the proof of our…
Radii of the uniformly convex of order of Lommel and Struve functions
Sercan Topkaya, Erhan Deniz, Murat Çağlar
In this paper, we determine the radii of uniformly convex of order for three kinds of normalized Lommel and Struve functions of the first kind. In the cases considered the…
The General Subclasses of the Analytic Functions and Their Various Properties
Sercan Topkaya, Nizami Mustafa
The object of the present paper is to introduce and investigate two new general subclasses and of the analytic…
Fekete-Szegö Problem For Generalized Bi-Subordinate Functions of Complex Order
S. Topkaya, E. Deniz
In this paper, we obtain Fekete-Szegö inequality for the generalized bi-subordinate functions of complex order. The results, which are presented in this study, would generalize tho…
