Fekete-Szego problem for starlike of complex functions of order b related to generalized derivative operator

الملخص EN

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 denoted by sbDG, (m,q,λ)O and cbDG, (m,q,λ)O respectively, which involving certain a generalized derivative operator DG, (m,q,λ)O defined in [8].

Various known or new special cases of our results are also pointed out.
