초록

Making use of the generalized integral operator, we define a new subclass of uniformly convex functions and a corresponding subclass of starlike functions with negative coefficients and obtain coefficients estimates, extreme points. Further let (formula) be the sequence of partical sums of the analytic functions (formula) and determine sharp lower bounds for (formula).

Abstract

Making use of the generalized integral operator, we define a new subclass of uniformly convex functions and a corresponding subclass of starlike functions with negative coefficients and obtain coefficients estimates, extreme points. Further let (formula) be the sequence of partical sums of the analytic functions (formula) and determine sharp lower bounds for (formula).
