Modified Hadamard product properties of certain class of analytic functions with varying arguments defined by Salagean and Ruscheweyh derivative [PDF]

open access: yes, 2017
In this paper we study the modified Hadamard product properties of certain class of analytic functions with varying arguments defined by S˘alăgean and Ruscheweyh derivative. The obtained results are sharp and they improve known results.

Designing Filter for Certain Subclasses of Analytic Univalent Functions [PDF]

open access: yes, 2018
In this paper we consider certain subclasses of analytic univalent functions and plot a frequency response of appropriate circuit for both amplitude and phase with changing source frequency.

On a subclass of convex functions [PDF]

open access: yes, 2016
In this paper we study a subclass of convex functions. Among others we prove an interesting property regarding the composition of functions from this class. The basic tool of the proof is the theory of differential subordination.

Notes on starlike log-harmonic functions of order α

open access: yes, 2013
For log-harmonic functions f(z) = zh(z)g(z) in the open unit disk U, two subclasses H*LH(α) and G*LH(α) of S*LH(α) consisting of all starlike log-harmonic functions of order α (0 ≤ α < 1) are considered. The object of the present paper is to discuss some
