A characterization of isometries on an open convex set, II

A characterization of isometries on an open convex set, II Let E n be an n-dimensional Euclidean space with n ≥ 2. In this paper, we generalize a classical theorem of Beckman and Quarles by proving that if a mapping, from an open convex subset Co of E n into E n , preserves a distance ρ, then the restriction of f to an open convex subset C ∞ of C 0 is an isometry. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of the Brazilian Mathematical Society, New Series Springer Journals

Abstract

Let E n be an n-dimensional Euclidean space with n ≥ 2. In this paper, we generalize a classical theorem of Beckman and Quarles by proving that if a mapping, from an open convex subset Co of E n into E n , preserves a distance ρ, then the restriction of f to an open convex subset C ∞ of C 0 is an isometry.
