Abstract

Let φ(z) be an analytic function with positive real part on ∆ =
{z; |z| < 1} with φ(0) = 1, φ
0
(0) > 0 which maps the unit disk ∆ onto
a region starlike with respect to 1 and symmetric with respect to the real axis. The radii of strong starlikeness of certain classes of analytic functions are computed.
