Bounds for initial maclaurin coefficients for a new subclasses of analytic and M-fold symmetric BI-univalent functions
(Işık University Press, 2020)
In the present paper, we introduce and study two new subclasses of the function class ?m consisting of analytic and m-fold symmetric bi-univalent functions in the open unit disk U. We establish upper bounds for the initial ...
On a class of sakaguchi functions related to Bernoulli lemniscate and modified sigmoid function
(Işık University Press, 2020)
The aim of this investigation is to provide further results on a class of Sakaguchi functions related to Bernoulli Lemniscate and modified sigmoid function for the class SL(s, t, Φm,n). Early few coefficient bounds of f(z) ...
Study of subclasses of starlike and convex functions
(Işık University Press, 2020)
In this article, we introduce new subclasses of starlike and convex functions by using a new differential operator defined in the open unit disk U. We study the geometric properties of such subclasses of starlike and convex ...
Fekete-Szegö inequality for analytic and bi-univalent functions subordinate to (p, q) −Lucas polynomials
(Işık University Press, 2021)
In this paper, a subclass of analytic and bi-univalent functions by means of (p, q) − Lucas polynomials is introduced. Certain coefficients bounds for functions belonging to this subclass are obtained. Furthermore, the ...
Certain subclass of Pascu-type bi-starlike functions in parabolic domain
(Işık University Press, 2021)
Estimates on the coefficients |a2| and |a3| are obtained for normalized analytic function f in the open disk with f and its inverse g = f?1 satisfy the condition that zf0(z) + ?z2f00(z)(1 ? ?)f(z) + ?zf0(z) and zg0(z) + ...
Subclasses of univalent functions related with functions of bounded radius rotation
(Işık University Press, 2023-04)
This investigation is in twofold. Firstly, a comprehensive generalization of starlike functions is initiated. This notion gives more insight to the study of functions with bounded radius rotation. In this direction, we ...
Coefficient estimates for new subclasses of meromorphic bi-univalent functions associated with linear operatör
(Işık University Press, 2022)
In this paper, we define a new differential linear operator of meromorphic bi-univalent functions class ??, and obtain the estimates for the coefficients |b?| and |b?|. Further we pointed out several new or known consequences ...
(p, q)−Chebyshev polynomials and their applications to bi-univalent functions
(Işık University Press, 2022)
In the present paper, a subclass of analytic and bi-univalent functions by means of (p, q)−Chebyshev polynomials is introduced. Certain coefficient bounds for functions belong to this subclass are obtained. Furthermore, ...
Upper bound for third Hankel determinant of a class of analytic functions
(Işık University Press, 2023-10)
We establish upper bounds for second Hankel determinant, the Fekete-Szegö functional and third Hankel determinant for normalized analytic functions f ? W?(?, ?),W?(?, ?) = { f : Re ((1 ? ? + 2?)f(z)/z+ (? ? 2?)f?(z) + ...
Application of Mittag–Leffler function on certain subclasses of analytic functions
(Işık University Press, 2023-10)
The purpose of the present paper is to find the sufficient conditions for some subclasses of analytic functions associated with Mittag-Leffler function to be in subclasses of k?ST[A, B] and k?UCV[A, B] involving Jack’s ...
