Abstract
In the present investigation, sharp upper bounds ofja3 a22j for functionsf(z) = z + a2z2 + a3z3 + belongingto certain subclas1ses of starlike and convex functions with respectto symmetric points are obtained. Also certain applications of themain results for subclasses of functions dened by convolution witha normalized analytic function are given. In particular, Fekete-Szego inequalities for certain classes of functions dened throughfractional derivatives are obtained.
