On Close - to - Convex Function and Univalent Function
Keywords:
Starlike, convex, univalency, regular function, close-to-convex, definitionsAbstract
Let f(z) = z + å¥n=2 anzn and g(z) be regular in the unit disk
E = {z : z < 1}. In this study, a condition under which Re gf ''((zz)) > 0 was establish and the result applied to discuss the univalency of the function f (z) . AMS (MOS) Subject
classification codes 30C45, 30C50.
