Some remarks on Möbius structures
V. V. Aseev Sobolev Institute of Mathematics, 4, Koptyuga ave., Novosibirsk, 630090, Russia
Abstract:
Some elementary relations between semimetrics in a Möbius structure allow us to give a correct definition of subspaces of a Möbius space and obtain the solutions in the problem of junction for Ptolemaic Möbius spaces as well as the problem of extending the Möbius structure from a subset to the whole set.
Keywords:
Möbius structure, Möbius space, ptolemaic semimetric, ptolemaic Möbius structure, Möbius equivalence of semimetrics.
