International Journal of Mathematics and Mathematical Sciences, 1982, vol. 5, 1-8

Abstract:

We consider the second coefficient of a class of functions, univalent and normalized, and with all derivatives univalent in the unit disk D , and improve on a known result. It is also shown that this bound is in a sense best possible.
