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 ...
Applications of chebyshev polynomials on ?-pseudo bi-starlike and ?-pseudo bi-convex functions with respect to symmetrical points
(Işık University Press, 2020)
The purpose of this work is to use the Chebyshev polynomial expansions to seek upper bounds for the second and third coefficients of functions belongs to a subclass of ?-pseudo bi-starlike and ?-pseudo bi-convex functions ...
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 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| ...
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 ...
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 ...
