A normed space with the BeckmanQuarles propertyJoseph M. LingUniversity of Calgary, Calgary, Alberta, Canada T2N 1N4, email: ling@math.ucalgary.caAbstract: Beckman and Quarles proved that a unit distance preserving mapping from a Euclidean space $\mathbf{E}^{n}$ into itself is necessarily an isometry. In this paper, we give an example of a (nonstrictly convex) normed space $H$ for which every unit distance preserving function from $H$ into itself is an isometry. Keywords: BeckmanQuarles theorem, isometry Classification (MSC2000): 51M05, 52A10, 52A20, 52C05, 52C25 Full text of the article:
