A new subclass of bi-univalent functions of complex order defined by the symmetric q-derivative and subordination
In this paper, we introduce a new subclass of bi-univalent functions of complex order, using the symmetric q-derivative with subordination principles. We obtain upper bounds for the coefficients |c2|, |c3| and estimate an upper bound for the Fekete–Szegő problem within this new subclass ˜MΣq(t,ϱ,ζ).
