Journal: Journal of Henan Normal University(Natural Science Edition)
Keyword: extreme point; subordination; inner function; convex function;
Abstract: In this paper we study the extremal problems for SK(α)(α≠1/2) .We obtain the resprestations of ex- treme point of closed convex hull of SK(α),as well as distortion theorems and coefficient extremates ofSK(α).
