INITIAL BOUNDS FOR CERTAIN CLASSES OF BI-UNIVALENT FUNCTIONS DEFINED BY THE (p,q)-LUCAS POLYNOMIALS
(Isik University, 2021) Magesh N.; Abirami C.; Altinkaya Ş.
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 purpose of this article is to make use of the (p,q) — Lucas polynomials Lp,q,n(x) and the generating function (Formula presented), in order to introduce three new subclasses of the bi-univalent function class ?. For functions belonging to the defined classes, we then derive coefficient inequalities and the Fekete-Szegö inequalities. Some interesting observations of the results presented here are also discussed. We also provide relevant connections of our results with those considered in earlier investigations. © Işık University, Department of Mathematics, 2021. all rights reserved.
