Webb28 juli 2014 · There are two definitions of star-shaped domain. One is given in wikipedia as follows. Def1: A set S in the Euclidean space R n is called a star domain (or star-convex set, star-shaped or radially convex set) if there exists x 0 in S such that for all x in S the line segment from x 0 to x is in S.

WebbIn 1946 Krasnoselskii proved that if every n + 1 points of a compact connected set S in a Euclidean space E n can see at least one point of S via S then S is starshaped [1]. 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.

The aim of this note is to prove that if 717" is a compact subset of En and for some m every w-dimensional hyperplane through a fixed point pQEn intersects M along a nonempty acyclic set, lúm^n — 1, then M is star-shaped with respect to p, i.e., if aQM
Webb24 mars 2024 · A subset X of R^n is star convex if there exists an x_0 in X such that the line segment from x_0 to any point in X is contained in X. A star-shaped figure is star convex but not convex (as can be seen by taking x_0 to be the center of the star.) A star convex set is always pathwise-connected, which in turn is always connected.
