Notes on the norm of pre-Schwarzian derivatives on bi-univalent functions of order
H. Mahzoon, R. Kargar
In the present paper we estimate the norm of the pre-Schwarzian derivative of bi-starlike functions of order where . Initially this problem was handled by Rahmatan e…
A note on the paper "Tang et al. [Bull Iran Math Soc (2019) doi:10.1007/s41980-019-00262-y]"
M. M. Motamedinezhad, Rahim Kargar
Very recently Tang et al. [Bull Iran Math Soc (2019) doi:10.1007/s41980-019-00262-y] have studied some majorization results for two certain subclasses of the starlike functions ass…
Notes on the norm of pre-Schwarzian derivatives of certain analytic functions
Rahim Kargar
In this paper, we obtain sharp bounds for the norm of pre--Schwarzian derivatives of certain analytic functions. Initially this problem was handled by H. Rahmatan, Sh. Najafzadeh a…
On certain subclasses of close-to-convex functions related with the second-order differential subordination
Hesam Mahzoon, Rahim Kargar
Let be the family of analytic and normalized functions in the open unit disc . In this article we consider the following classes \begin{equation*} \mathcal{R}(…
Further results for a subclass of univalent functions related with differential equation
Hesam Mahzoon, Rahim Kargar
Let denote the class of functions analytic in the open unit disc , normalized by the condition and satisfying the inequality \begin{equation*} \left|zf'…
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…
