چکیده
|
In the present investigation, we introduce the two subclasses sασ(γ, ρ, λ, µ, ξ, δ) and sσ(γ, ρ, λ, µ, ξ, δ; β) of normalized analytic bi-univalent functions defined in the open unit disk and associated with the ruscheweyh’s operator. further, we obtain bounds for the second and third taylor-maclaurin coefficients of the functions belong to these subclasses. we also provide relevant connections with earlier investigations of other researchers.
