The radius of -convexity of normalized Bessel functions of the first kind
Árpád Baricz, Halit Orhan, Róbert Szász
The radii of -convexity are deduced for three different kind of normalized Bessel functions of the first kind and it is shown that these radii are between the radii of starliken…
Radii of starlikeness of some special functions
Árpád Baricz, Dimitar K. Dimitrov, Halit Orhan +1
Geometric properties of the classical Lommel and Struve functions, both of the first kind, are studied. For each of them, there different normalizations are applied in such a way t…
-Neighborhood for some families of analytic and multivalent functions
Halit Orhan
In the present investigation, we give some interesting results related with neighborhoods of p-valent functions. Relevant connections with some other recent works are also pointed…
Fekete-Szegö problem for certain classes of Ma-Minda bi-univalent functions
Halit Orhan, N. Magesh, V. K. Balaji
In the present work, we propose to investigate the Fekete-Szegö inequalities certain classes of analytic and bi-univalent functions defined by subordination. The results in the bou…
