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-Szeg?o problem within this new subclass
