The only functions in St that satisfy Re J(f)=max {Re J(g): g E St} are Koebe functions and there are only a finite number of them. Introduction. We shall be concerned with the closed convex hulls of various families of functions that are analytic and univalent in the open unit disk A ={z E C: Iz < 1}.

This estimate depends only on the outer and inner radii of the domain, and on the minimum curvature radius of its boundary.
