C is star convex (star-shaped) if there exists an x0 in C such that the line segment from x0 to any point y in C is contained in C. Hence a non-empty convex set is always star-convex but a star-convex set is not always convex.

This result was expanded by Robkin in 1965 [2]. In this paper, we characterize starshaped sets in E n by a local arcwise convexity property relative to a point p.
