The radius of univalence of certain analytic functions
The second coefficient of a function with all derivatives univalent.
The sharp version of a criterion for starlikeness related to the operator of Alexander
The method of convolution is used to determine a sharp condition for starlikeness of analytic functions defined in the unit disc U = {z ∈ ℂ: |z| < 1} and having the property f(0) = f'(0) - 1 = 0. The integral version is given using the Alexander integral operator.
