Convolution conditions for bounded α-starlike functions of complex order

Abstract

Let A be the class of analytic functions in the unit disc U of the complex plane C with the normalization f(0)=f′(0)−1=0. We introduce a subclass S∗M(α,b) of A, which unifies the classes of bounded starlike and convex functions of complex order. Making use of Salagean operator, a more general class S∗M(n,α,b) (n≥0) related to S∗M(α,b) is also considered under the same conditions. Among other things, we find convolution conditions for a function f∈A to belong to the class S∗M(α,b). Several properties of the class S∗M(n,α,b) are investigated.
