ON ANALYTIC FUNCTIONS SUBCLASS DEFINED BY DIFFERENTIAL OPERATOR
ON ANALYTIC FUNCTIONS SUBCLASS DEFINED BY D. O.
Resumen
In this work, we present a novel differential operator-defined a specific set of negative-coefficient analytic univalent functions. For this class, we get subordination results, integral means inequalities, extreme points, and coefficient inequalities.
