Certain classes of analytic functions concerned with uniformly starlike and convex functions

摘要

Applying the coefficient inequalities of functions f(z) belonging to the subclasses MD(α,β)andND(α,β) of certain analytic functions in the open unit disk U, two subclasses MD∗(α,β)andND∗(α,β) are introduced. The object of the present paper is to derive some convolution properties of functions f(z) in the classes MD∗(α,β)andND∗(α,β).
