On the first-order differential subordination and superordination results for -valent functions
V. S. Masih, A. Ebadian, Sh. Najafzadeh
In this paper, we obtain some application of first-order differential subordination, superordination and sandwich-type results involving operator for certain normalized -valent…
Radii of convexity of integral operators
P. Najmadi, Sh. Najafzadeh, A. Ebadian
The object of the present paper is to study of radius of convexity two certain integral operators as follows \begin{equation*} F(z):=\int_{0}^{z}\prod_{i=1}^{n}\left(f'_i(t)\right)…

P. Najmadi, Sh. Najafzadeh, A. Ebadian
The object of the present paper is to study of two certain subclass of analytic functions related with Booth lemniscate which we denote by and .…
Controlled K-frames in Hilbert Spaces
Asghar Rahimi, Shahram Najafzadeh, Mohamad Nouri
K-frames were recently introduced by L. Gǎvruta in Hilbert spaces to study atomic systems with respect to bounded linear operator. Also controlled frames have been recently introdu…
Controlled K-frames and their invariance under Compact Perturbation
Asghar Rahimi, Shahram Najafzadeh, Mohamad Nouri
K-frames were recently introduced by L. Gǎvruta in Hilbert spaces to study atomic systems with respect to bounded linear operator. Also controlled frames have been recently introdu…
Stability of the Jensen--type functional equation in ternary Banach algebras: An alternative fixed point approach
A. Ebadian, Sh. Najafzadeh
Using fixed point methods, we prove the generalized Hyers--Ulam--Rassias stability of ternary homomorphisms, and ternary multipliers in ternary Banach algebras for the Jensen--type…
Certain Subclasses of Convex functions with positive and missing Coefficients by using a fixed point
Sh. Najafzadeh, M. Eshaghi Gordji, A. Ebadian
By considering a fixed point in unit disk , a new class of univalent convex functions is defined. Coefficient inequalities, integral operator and extreme points of this class ar…
