文摘

In the present paper certain subclasses of close-to-convex functions are investigated. In particular, we obtain an estimate for the Fekete–Szeg? functional for functions belonging to our class, coefficient estimates and a sufficient condition. The results presented here would provide extensions of those given in some earlier works.
