文摘The author considers a new class SHλum（α） of normalized analytic functions defined by a differential operator. Several basic properties and characteristics of the functions belonging to the class SHλum（α） are investigated. These include integral rep- resentations, coefficient bounds, the Fekete^Szeg5 problem, class-preserving operators and Tg-neighborhoods.
