Abstract:

Let F(a,b;c;z) be the Gaussian hypergeometric function and I_a,b;c(f)=zF(a,b;c;z)*f(z) be the Hohlov operator defined on the class A of all normalized analytic functions. We determine conditions on the parameters a,b,c such that I_a,b;c(f) will be in the class of parabolic starlike functions S_p(α,β). Our results extend several earlier results.
