The coefficient estimates including the classical Fekete-Szego inequality of functions belonging to this class are then derived. The results presented in this paper are the generalization of the results that given in [27].eninfo:eu-repo/semantics/closedAccessAnalytic FunctionsFekete-Szego ProblemPrinciples of SubordinationQuasi-SubordinationSakaguchi FunctionMajorizationSalagean Derivative OperatorArticle
