Abstract: In the present investigation, we introduce the subclasses ΛΣ (η,h, φ) and ΛΣ (η,h, δ) of m-fold symmetric bi-univalent function class Σm, which are associated with the pseudo-starlike functions and defined in the open unit… read more here.

Abstract: Let Tm denote the class of m -fold symmetric bi-univalent functions in the open unit disk. We obtain the coefficient bounds of |am+1| and |a2m+1| for functions in a new general subclass C h,p m… read more here.
