Abstract

In this study, we introduce and study the $(n, δ)$ neighborhoods of subclasses $S_n (γ, λ, β, η) R_n (γ, λ, β, μ, η) S_n^α (γ, λ, β, μ, η)$ and $R_n^α (γ, λ, β, μ, η)$ of the class A(n) of normalized analytic functions in $U = {z ∈ ℂ : |z|<1}$ with negative coefficients, which are defined by using of the generalized Ruscheweyh derivative operator.

Keywords:

Analytic functions, convex functions, neighborhoods generalized ruscheweyh derivative, Star like functions, univalent functions,
