Coefficient Estimates for New Subclasses of Analytic and Bi-Univalent Functions Defined by Al-Oboudi Differential Operator

摘要

We introduce and investigate two new subclasses𝒩Σδ,μn,α,λand𝒩Σδ,μn,β,λof analytic and bi-univalent functions in the open unit disk𝕌.For functions belonging to these classes, we obtain estimates on the first two Taylor-Maclaurin coefficientsa2anda3.
