Fekete -Szego Problem for Starlike of Complex functions of Order 풃 Related to Generalized Derivative Operator

Abstract

The purpose of the present paper is to investigate the Fekete-Szego problem for certain new subclasses starlike and convex functions of complex of order 푏 denoted by , ( ,,) b s mq a d l and , ( ,,) b c mq a d l respectively, which involving certain a generalized derivative operator , ( ,,) m q a d l defined in [8]. Various known or new special cases of our results are also pointed out.
