Abstract
It is an elementary fact that if we fix an arbitrary set of affine independent points in , then the Euclidean distances determine the point in uniquely. In this paper we investigate a similar problem in general normed spaces which is motivated by this known fact. Namely, we characterize those, at least -dimensional, real normed spaces such that for every set of affine independent points , the distances determines the point lying in the simplex uniquely. Surprisingly, the characterization depends on .
