摘要
Consider the family of locally univalent analytic functions h in the unit disk |z|<1 with the normalization h(0)=0, h '(0)=1 and satisfying the condition Re(zh ''(z)/alpha h '(z))<1/2 for z is an element of D, where 0 < alpha <= 1. The aim of this article is to show that this family has several elegant properties such as involving Blaschke products, Schwarzian derivative and univalent harmonic mappings.
