On quasi-convex functions and related topics
Let S be the class of functions f which are analytic and univalent in the unit disc E with f(0)=0, f′(0)=1. Let C, S* and K be the classes of convex, starlike and close-to-convex functions respectively. The class C* of quasi-convex functions is defined as follows:
