ON A COEFFICIENT PROBLEM OF ANALYTIC SYMMETRIC FUNCTIONS
초록
Through the paper, we consider functions f analytic in the unit disk D={z:vertical bar z vertical bar <1} normalized by f(0)=0 and f'(0)=1. Following Rogosinski [5], we let T denote the class of all typically-real functions f which preserve half-plane in the following sense.
