We say that fe Sk, 0--< k< 1, if fe S and f has a quasiconformal extension on the whole plane (7 with complex dilatation izf= f~/fz that satisfies Ipc (z) l--< k almost everywhere in (7. The symbols fz, f~ denote formal derivatives of f. Let S*(a), O-< a< 1, denote the subclass of S consisting of strongly starlike functions of order a, cf.[1],[5], ie of functions f that satisfy: zf'(z) 7r arg f-~-y---< a~, z~ A.(1)
