Abstract
Let be the integral operator defined by where each of the functions and are, respectively, analytic functions and functions with positive real part defined in the open unit disk for all . The object of this paper is to obtain several univalence conditions for this integral operator. Our main results contain some interesting corollaries as special cases.

Summary
BBββ be the integral operator de ned by We obtain new sufficient conditions for the univalence of the general integral operator BBββ(zz) de ned by zz nn ttββ−1 Note that the integral operator BBββ generalizes the following operators introduced and studied by several authors: (1) If we let ζζii = 0, for all ii = 1, ...
