A Certain Subclass of Multivalent Analytic Functions with Negative Coefficients for Operator on Hilbert Space
Keyword(s):
In the present work, we introduce and study a certain subclass for multivalent analytic functions with negative coefficients defined on complex Hilbert space. We establish a number of geometric properties, like, coefficient estimates, convex set, extreme points and radii of starlikeness and convexity.
