摘要：
In the present paper, sharp initial coefficient bounds have been estimated for functions in the newly defined classes S-gamma,delta(k)(Phi) and S-gamma,delta,h(k)(Phi), which in fact, unifies many earlier known classes. Further, sharp bounds of the Fekete-Szego coefficient functional for functions in the classes introduced here are obtained and special cases of our results are also pointed out.
