Applications of chebyshev polynomials on λ-pseudo bi-starlike and λ-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 λ-pseudo bi-starlike and λ-pseudo bi-convex functions ...
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) + λz2f00(z)(1 − λ)f(z) + λzf0(z) and zg0(z) + ...
On the Chebyshev polynomial coefficient problem of bi-Bazilevič functions
(Işık University Press, 2020)
A function said to be bi-Bazilevič in the open unit disk U if both the function and its inverse are Bazilevič there. In this paper, we will study a newly constructed class of bi-Bazilevič functions. Furthermore, we establish ...
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, ...
