Abstract: The object of this paper to study the class WH(n,p,α,λ,θ,q) of multivalent functions defined by Hadamard product in the open unit disk U={z∈C:|z|<1}. We obtain some geometric properties for this class, like, coefficient estimate, closure theorem, extreme points, distortion theorem and modified Hadamard products.

Keywords: Multivalent function; Hadamard product; Closure theorem; Distortion theorem; Extreme points; Modified hadamard products. (search for similar items in EconPapers)
