Subclass of analytic functions on q-analogue connected with a new linear extended multiplier operator

open access: yes
Using a new linear extended multiplier q-Choi-Saigo-Srivastava operator we define a subclass subordination and the newly defined q-analogue of the Choi-Saigo-Srivastava operator to the class of analytic functions.

Radii of harmonic mapping with fixed second coefficients in the plane

open access: yes, 2018
In this paper we investigate the radii problem for harmonic functions with a fixed coefficient and determine the radii of univalence, stable starlikness, stable convexity, fully starlikness and fully convexity of order α for these type of functions.

Radius of starlikeness through subordination

open access: yes, 2023
A normalized function f on the open unit disc is starlike (or convex) univalent if the associated function zf/(z)/f (z) (or 1+zf//(z)/f/(z)) is a function with positive real part.

Generalized q-Srivastava-Attiya operator on multivalent functions

open access: yes
In this article, we define a generalized q-integral operator on multivalent functions. It generalizes many known linear operators in Geometric Function Theory (GFT).

New Coefficient Conditions for Functions Starlike with Respect to Symmetric Points [PDF]

open access: yes, 2010
2000 Mathematics Subject Classification: Primary 30C45, secondary 30C80.We consider some familiar subclasses of functions starlike with respect to symmetric points and obtain sufficient conditions for these classes in terms of their Taylor coefficient ...

Certain sufficient conditions for parabolic starlike and uniformly close-to-convex functions

open access: yes, 2016
In the present paper, we study certain differential subordinations and obtain sufficient conditions for parabolic starlikeness and uniformly close-toconvexity of analytic functions.

Letter to the Editor. Remarks on Some Inequalities for Polynomials [PDF]

open access: yes, 2013
MSC 2010: 30A10, 30C10, 30C80, 30D15, 41A17.In the present article, I point out serious errors in a paper published in Mathematica Balkanica three years ago. These errors seem to go unnoticed because some mathematicians are applying the results stated in

Starlikeness and close-to-convexity involving certain differential inequalities

open access: yes
In the present paper, we study certain differential inequalities involving meromorphic functions in the open unit disk and obtain certain sufficient conditions for starlikeness and close-to-convexity of meromorphic functions.

Subordination and superordination results for the family of Jung-Kim-Srivastava integral operators

open access: yes, 2010
In this paper, we derive some subordination and superordination results associated with the family of Jung-Kim-Srivastava integral operators defined on the space of meromorphic functions. Several sandwich-type results are also obtained.
