Abstract:

Let Ω be a set in the complex plane C. Also let p be analytic in the upper half-plane Δ={z:z∈C and Im(z)>0} and suppose that ψ: C3×Δ→C. In this paper, we consider the problem of determining properties of functions p that satisfy the following differential superordination Ω⊂{ψ(p(z), p'(z), p"(z);z): z∈Δ}. Applications of these results to differential subordination and differential superordination for analytic functions in Δ are also presented.

Key words: Differential subordination, Differential superordination, Analytic functions, Admissible functions, Upper half-plane
