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