Certain subclasses of analytic functions with varying arguments

open access: yesLe Matematiche, 2014
In this paper, we introduce new classes VM(β ) and VN(β ) of analytic functions with varying arguments in the open unit disc U = {z ∈ C : |z| <1}. Some properties such as coefficient estimates, extreme points, distortion theorems for functions f (z ...
