On a new subclass of bi-univalent functions defined by using Salagean operator


Abstract: In this manuscript, by using the Salagean operator, new subclasses of bi-univalent functions in the open unit disk are defined. Moreover, for functions belonging to these new subclasses, upper bounds for the second and third coefficients are found.

Keywords: Univalent functions, bi-univalent functions, coefficient bounds and coefficient estimates, Salagean operator
