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 ...
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 Σm consisting of analytic and m-fold symmetric bi-univalent functions in the open unit disk U. We establish upper bounds for the initial ...
