Abstract

This study examines and investigates two novel subclasses ℳ𝓗Σ𝓆(Ѳ, Ғ, η; δ) and ℳ𝓗~Σ𝓆(θ, Ғ, η; φ) for a family Σ𝓆 of K-fold symmetric bi-univalent function in a open unit disk. Furthermore, where function in these subclasses, bound of coefficient |𝒷𝓆⏆𝟙| and |𝒷𝟚𝓆⏆𝟙| were derived. Moreover, several refined results are presented for related classes.
