Abstract

In this work, used (β, ζ)-Lucas polynomials that involve the modified sigmoid activation function ψ(δ) to develop a family of analytic functions along with Sălăgean-type bi-univalent functions. And obtain upper bounds for functions that belong to these subclasses. Furthermore, Fekete-Szegö inequality for these families is discussed.
