QUASISYMMETRIC FUNCTIOI{S OF EXTREMAL GROWTH

Abstract

In this paper we continue the study of the growth of quasisymmetric func-tions started in [2] and [3] by W. K. Hayman and the author. An increasing homeo-morphism/of the real line R onto itself is called K-quasisymmetric (r(-qs) if (1.r) l=f,(:!'),,fQ)=*K- f(x)-f(x-r)-^
