Resumen de Su±cient conditions for starlikeness of order ®

Nailah M. AlDihan, Teodor Bulboaca

• In this paper we obtain some su±cient conditions for an analytic function to be starlike of order ®, by using the di®erential operator recently introduced by F. Al- Oboudi. For such classes we also give some applications of a result due to M. Robert- son.
