Neighborhoods of starlike and convex functions associated with parabola.
2000 Mathematics Subject Classification: Primary 30C45, secondary 30C80.We consider some familiar subclasses of functions starlike with respect to symmetric points and obtain sufficient conditions for these classes in terms of their Taylor coefficient. This leads to obtain several new examples of these subclasses.
MSC 2010: 30C45The object of the present paper is to discuss some radius properties.
