Abstract
Examples of application in a metric space and a space with indefinite metric of the universal multipoint invariant (UMP invariant) known as the Cayley – Menger determinant for four points are considered. Such an invariant, as the results show, determines the metric structure of the Euclidean and pseudo-Euclidean spaces of dimension n=2. For these spaces, expressions for UMP invariants associated with the use of appropriate pseudo distances are also obtained and analyzed. The considered approach can be applied also in spaces with dimension n>2. Cite as: D. O. Dziakovych, “Application of universal multipoint invariants in Euclidean and pseudo-Euclidean spaces,” Prykl.
