Initial Coefficient Bounds for Bi-Close-to-Convex Classes of n-Fold-Symmetric Bi-Univalent Functions
In this article, the strong class of bi-close-to-convex functions of order α and β in n-fold symmetric bi-univalent functions, which is the subclass of σ, is introduced. The upper bound value for an+1, a2n+1 for functions in these classes are obtained. Moreover, the Fekete–Szegö relation for our classes of functions are established.
