Abstract

A consistent path system in a graph GG is an collection of paths, with exactly one path between any two vertices in GG. A path system is said to be consistent if it is intersection-closed. We say that GG is strictly metrizable if every consistent path system in GG can be realized as the system of unique geodesics with respect to some assignment of positive edge weight. In this paper, we show that the family of strictly metrizable graphs is minor-closed.
