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 ...
Coeffıcient estimates for bi-univalent ma-minda type functions associated with q-derivative
(Işık University Press, 2021)
In this article, we consider a new subclasses of analytic and bi-univalent functions associated with q-derivative in the open unit disk. We obtain coefficient bounds for the Taylor-Maclaurin coefficients |a2| and |a3| of ...
(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, ...
Initial bounds for certain classes of bi-univalent functions defined by the (p, q)-lucas polynomials
(Işık University Press, 2021)
Our present investigation is motivated essentially by the fact that, in Geometric Function Theory, one can find many interesting and fruitful usages of a wide variety of special functions and special polynomials. The main ...
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) + ...
On the coefficient bounds for a subclass of bi-univalent functions by using S?l?gean differential operators
(Işık University Press, 2023-10)
Making use of S?l?gean differential operator, in this paper, we introduce and investigate an interesting subclass Sh,p? (k, ?) of bi-univalent functions in the open unit disk U. Furthermore, we find estimates on the |a2| ...
A subclass of bi-univalent functions related to shell-like curves connected with Fibonacci numbers associated with (p, q)-derivative
(Işık University Press, 2023-10)
In this paper, we define a new subclass of bi-univalent functions related to shell-like curves connected with Fibonacci numbers by using (p, q)-derivative and the coefficient estimates, Fekete-Szego inequalities are discussed ...
On the Chebyshev polynomial coefficient problem of bi-Bazilevi? functions
(Işık University Press, 2020)
A function said to be bi-Bazilevi? in the open unit disk U if both the function and its inverse are Bazilevi? there. In this paper, we will study a newly constructed class of bi-Bazilevi? functions. Furthermore, we establish ...
The Fekete-Szegö problems for a subclass of m-fold symmetric bi-univalent functions
(Işık University Press, 2021)
In this paper, we investigate a new subclass P??? ?m(?, ?) of m-fold symmetric bi-univalent functions. Moreover, for functions of this subclass, we obtain the coefficient estimates of the Taylor-Maclaurin coefficients ...
On coefficient estimates for certain subclasses of bi-univalent functions
(Işık University Press, 2023-10)
We introduce certain subclasses of bi-univalent functions related to the generalized Janowski functions and estimate the general coefficient bound for the newly defined classes. Also, we deduce certain new results and the ...
