  Abstract:

In this paper we consider the classes of starlike functions, starlike functions of order $ alpha$, convex functions, convex functions of order $ alpha$ and the classes of the univalent functions denoted by $ SHleft(betaright)$, $ SP$ and $ SPleft(alpha, betaright)$. On these classes we study the convexity and $ alpha$- order convexity for a general integral operator.;
