Coefficient Estimates for Initial Taylor-Maclaurin Coefficients for a Subclass of Analytic and Bi-Univalent Functions Defined by Al-Oboudi Differential Operator
Keyword(s):
We introduce and investigate an interesting subclass𝒩𝒫Σλ,δ(n,β;h)of analytic and bi-univalent functions in the open unit disk𝕌. For functions belonging to the class𝒩𝒫Σλ,δ(n,β;h), we obtain estimates on the first two Taylor-Maclaurin coefficientsa2anda3.
