Abstract

In the present paper, we study certain subclasses Tp α, δ (μ, q, λ, γ, β) and Cp α, δ (μ, q, λ, γ, β) of analytic p-valent functions with negative coefficients in the unit disc. The results presented here include the modified Hadamard product, the radii of close-to-convexity, starlikeness and convexity for functions belonging to the above mentioned subclasses.
