Two Inclusive Subfamilies of bi-univalent Functions.

The aim of this article is to establish two new and qualitative subfamilies F(ε, κ, ℵ) and G(ε, κ, ℵ) of biunivalent functions. For functions in these subfamilies, we determine the first two Maclaurin coefficient estimations |C₂| and |C₃|, and address the Fekete-Szegö problem. Additionally, we mention some corollaries related to the main results. [ABSTRACT FROM AUTHOR]
