Abstract
We show that under certain mild conditions, a metric simplicial complex which satisfies
the Ptolemy inequality is a CAT(0) space. Ptolemy’s inequality is closely related to inversions
of metric spaces. For a large class of metric simplicial complexes, we characterize
those which are isometric to Euclidean space in terms of metric inversions.
