Denote by A the class of functions f(z) analytic in the unit disk D and normalised so that f(0) = f'(0) - 1 = 0. For f(z) is-an-element-of A, let F(z) = integral-z/0 [f(t)/t]dt for z is-an-element-of D. We find estimate on beta so that Re f'(z) > - beta will ensure the starlikeness of F(z). Our con...
