Certain New Subclassess of Analytic and Bi-univalent Functions
Certain New Subclassess of Analytic and Bi-univalent Functions
The paper presents two novel subclasses of the function class Σ, which consists of bi-univalent functions defined in the open unit disk D={ζ:|ζ|<1}. The authors investigate the properties of these new subclasses and provide estimates for the absolute values of the second, third, and fourth Taylor-Maclaurin coefficients r2, r3, and …
