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.
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 radius of uniform convexity of Bessel functions
Erhan Deniz, Róbert Szász
In this paper, we determine the radius of uniform convexity for three kinds of normalized Bessel functions of the first kind. In the mentioned cases the normalized Bessel functions…
Univalence and quasiconformal extension of an integral operator
S. Kanas, E. Deniz, H. Orhan
In this paper we give some sufficient conditions of analyticity and univalence for functions defined by an integral operator. Next, we refine the result to a quasiconformal extensi…
Radii of starlikeness and convexity of regular Coulomb wave functions
Árpád Baricz, Murat Çağlar, Erhan Deniz +1
In this paper our aim is to determine the radii of univalence, starlikeness and convexity of the normalized regular Coulomb wave functions for two different kinds of normalization.…
