Coefficient Estimates for Initial Taylor-Maclaurin Coefficients for a Subclass of Analytic and Bi-Univalent Functions Defined by Al-Oboudi Differential Operator [PDF]
The Scientific World Journal, 2013 We introduce and investigate an interesting subclass 𝒩𝒫Σλ,δ(n,β;h) of analytic and bi-univalent functions in the open unit disk 𝕌. For functions belonging to the class 𝒩𝒫Σλ,δ(n,β;h), we obtain estimates on the first two Taylor-Maclaurin coefficients a2 ...

Faber polynomials estimates for bi-univalent functions of complex order involving q-derivative [PDF]
, 2023 In this paper, we define a new subclass of bi-univalent functions of complex order which is defined by subordination in the open unit disc D by using operator. Furthermore, using the Faber polynomial expansions, we get upper bounds for the coefficients
