A unified class of k-uniformly convex functions defined by the Dziok–Srivastava linear operator

摘要

The main purpose of this paper is to introduce a new class UH(q,s,λ,β,k) of functions which are analytic in the open unit disk Δ={z:z∈Cand|z|<1}. We obtain various results including characterization, coefficient estimates, and distortion and covering theorems, for functions belonging to the class UH(q,s,λ,β,k).
