Coefficient Estimates for Subclasses of Bi-Univalent Functions

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2018
 In the present paper, we introduce two new subclasses of  the class consisting of analytic and bi-univalent functions in the open unit disk . Also, we obtain the estimates on the Taylor-Maclurin   coefficients and for functions in these subclasses. We obtain new special cases for our results.

(p, q)-Lucas polynomials and their applications to bi-univalent functions

Proyecciones (Antofagasta), 2019
In the present paper, by using the Lp,q,n(x) functions, our methodology intertwine to yield the Theory of Geometric Functions and that of Special Functions, which are usually considered as very different fields. Thus, we aim at introducing a new class of bi-univalent functions defined through the (p, q)-Lucas polynomials.
