Abstract
Let S be the class of functions f(z) which are analytic and univalent
in the open unit disk U with f(0) = 0 and f'(0) = 1. The nth partial s
ums of the Libera integral operator F(z) for f(z) is an element of S a
re denoted by S-n(z, F). In the present paper, the starlikeness proper
ty of S-n(z, F) is proved. (C) 1997 Academic Press.
