A subclass of parabolic starlike and uniformly convex functions

摘要

Let A be the class of analytic functions in the open unit disk U. A function f in A satisfying the normalization is said to be in the class SPn if Dnf is a parabolic starlike function, where Dn is a notation of the Salagean operator. In this paper, several basic properties and characteristics of the class SPn are investigated. These include subordination, convolution properties, class-preserving integral operators, and Fekete-Szegö problems.
