Sharp coefficients bounds for Starlike functions associated with Gregory coefficients
Sercan Kazımoğlu, Erhan Deniz, Hari Mohan Srivastava
In this paper we introduced the class of analytic functions which is related with starlike functions and generating function of Gregory coefficients. By u…
Geometric Properties of function
Sercan Kazımoğlu, Erhan Deniz
In this paper our aim is to find the radii of starlikeness and convexity for three different kind of normalization of the $N_ν(z)=az^{2}J_{ν}^{\prime \prime }(z)+bzJ_{ν}^{\prime}(z…
The solution of the Brannan conjecture
Erhan Deniz, Murat Çaglar, Róbert Szász
We make the final step to give a proof for the Brannan's conjecture. The basic tool of the study is a Mac-Laurin development and an adequately estimation of an integral.
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…
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…
