\(T\)-neighborhoods in various classes of analytic functions. (English) Zbl 1304.30025

The authors obtain various properties of different subclasses of analytic functions in the unit disc. In particular, they generalize previous work of many authors. It is interesting to note that they find the \(T\)-factor with respect to the class of univalent functions and the class of convex functions.
