Certain Results on a Subclass of Close-to-convex Functions
Abstract. In this paper we introduce and study a subclass of close-to-convex functions defined in the open unit disk. We establish the inclusion relationship, coefficient estimates and some sufficient conditions for a normalized function to be in our classes of functions. Furthermore, we discuss Fekete-Szegő problem for a more generalized class. The results presented here would provide extensio...
متن کاملOn certain subclass of meromorphic close-to-convex functions
In this paper we introduce and investigate a certain subclass of functions which are analytic in the punctured unit disk and meromorphically close-to-convex. The sub-ordination property, inclusion relationship, coefficient inequalities, distortion theorem and a sufficient condition for our subclass of functions are derived. The results presented here would provide extensions of those given in e...

متن کاملOn Certain Properties for a Subclass of Close–to–convex Functions
In the present paper, we introduce and investigate an interesting subclass K λ s (h) of analytic and close-to-convex functions in the open unit disk U . For functions belonging to the class K λ s (h) , we derive several properties as the convolution, the coefficient bounds, the covering theorem, the inclusion relationships as well as distortion theorem. The various results presented here would ...
