Abstract:
A projection of a vertex x of a graph G over a subset S of vertices is a vertex of S at minimal distance from x. The study of projections over quasi-intervals gives rise to a new characterization of quasi-median graphs.
Keywords:
generalized median graphs, Hamming graphs, quasi-median graphs, quasi-Hilbertian graphs
