Series of univalent functions [PDF]

Mathematical Notes of the Academy of Sciences of the USSR, 1978
We are considering a class S of functions F(z), F(0) = 0, F′(0) = 1 that are univalent and regular in the circle ¦z¦ < 1, and its subclasses s h * and K of starlike functions of order h and of convex functions respectively. Among others, we establish the following results: If F(z)es and 0 < α < 1, then IfF (z) e s (0 < a < 1) and $$\begin ...
