Abstract.   Let S*(1-b), (b 0 complex) denote the class of functions f(z) = z + a2z2 + ... analytic in D = {z : |z| < 1} which satisfies for z = eiθ D, f(z) / z 0 in D, and

Re[1 + 1/b(z f'(z) / f(z) - 1)] > 0.

The aim of this paper is to give the Koebe domain of the above mentioned class.

2000 Mathematics Subject Classification.   30C45.

Key words and phrases.   Univalent functions, starlike functions, starlike functions of comlex order, Montel normalization, Koebe domain.
