Abstract / Bemerkung
We study a certain metric d on R-n that was recently introduced by Nieto, Torres and Vazquez-Trasande [1], give a simple proof for the triangle inequality, and describe when exactly d(p, q) = d(p, r) + d(r, q) holds for some p, q, r is an element of R-n. Remarkably, one has d(p, q) = 2 for some p, q is an element of R-n if and only if 0 = p + q not equal p holds, in which case, one has also d(p, q) = d(p, r) + d(r, q) for all r is an element of R.
