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…
Coefficient and Fekete-Szegö problem estimates for certain subclass of analytic and bi-univalent functions
Hesam Mahzoon
In this paper, we obtain the Fekete-Szegö problem for the -th root transform of the analytic and normalized functions satisfying the condition \begin{equation*} 1…
