Abstract

Mathematics Physical Sciences Science & Technology
Making use of the Hadamard product (or convolution), we define a new subclass of uniformly starlike functions with respect to symmetric points and with negative coefficients. Coefficient estimates, extreme points, radii of close to convexity, starlikeness and convexity are obtained. Finally the class preserving integral operators is considered.
