Abstract

This paper introduces univalent functions defined on a unit disc Ų = {2 ∈ C :|2|<1} of analytic functions. Coefficient estimates are present, which belong to the class Ş * Ç(ς,σ,δ) and ŢŞ * Ç(ς,σ,δ), and other properties like distortion are derived for the class Ş * Ç(ς,σ,δ). Additionally, extreme points for the class Ş * Ç(ς,σ,δ) are also given.
