Abstract

We introduce a subclass $S_s^{({\kappa})}$ (A,B) (-1 ${\leq}$ B < A ${\leq}$ 1) of functions which are analytic in the open unit disk and close-to-convex with respect to ${\kappa}$ -symmetric points. We give some coefficient inequalities, integral representations and invariance properties of functions belonging to this class.

Keywords

close-to-convex functions; Janowski type; sakaguchi functions; k-symmetric points;
