On starlike functions related with the convex conic domain
R. Kargar, J. Sokół
In the present paper, we study a new subclass of --valent functions and obtain some inequalities concerning the coefficients for the desired class. Also, by…
On a certain subclass of strongly starlike functions
R. Kargar, J. Sokół, H. Mahzoon
Let , where , represent the class of functions that are analytic in the open unit disk , normalized by $f(0) = f'(0) -…
Some new inequalities for univalent functions
M. M. Motamedinezhad, R. Kargar
By use of a modified Nunokawa's lemma, we obtain some new conditions for univalence. Also, some sharp inequalities concerning univalent functions are presented.
Some applications of differential subordination for certain starlike functions
R. Kargar, L. Trojnar-Spelina
We consider the class of normalized starlike functions analytic in the open unit disk that satisfying the inequality \begin{equation*} \left|\left(…
On logarithmic coefficients of certain starlike functions related to the vertical strip
Rahim Kargar
In the present paper two certain subclasses of the starlike functions associated with the vertical strip are considered. The main aim of this paper is to investigate some basic pro…
Volterra type integral operator and analytic function spaces
Rahim Kargar
We investigate the geometric properties of the Volterra-type integral operator \begin{equation*} T_g[f](z) = \int_{0}^{z} f(s)\, g'(s)\, ds, \quad |z|<1, \end{equation*} acting on…
Some inequalities for a certain subclass of starlike functions
R. Kargar, H. Mahzoon, N. Kanzi
In 2011, Sokół (Comput. Math. Appl. 62, 611--619) introduced and studied the class as a certain subclass of starlike functions, consists of all functions ($f(…
Further results for starlike functions related with Booth lemniscate
R. Kargar, A. Ebadian, L. Trojnar-Spelina
In this paper we investigate an interesting subclass () of starlike functions in the unit disk . The class was introduced by Karga…
