Inclusive Subclasses of Bi-Univalent Functions Defined by Error Functions Subordinate to Horadam Polynomials

In this paper, by utilizing error functions subordinate to Horadam polynomials, we introduce the inclusive subclasses A(a, ?,r, u, ?, ?, ?), B(a, ?,r, u, ?, ?) and C(a, ?,r, u, ?, ?) of bi-univalent functions in the symmetric unit disk U. For functions in these subclasses, we derive estimations for the Maclaurin coefficients |k2| and |k3|, as well as the Fekete?Szeg? functional. Additionally, some related results are also obtained.
