WebA reflexive graph is a graph whose every vertex is endowed with a distinguished loop (Fig. 4).As objects, reflexive graphs are the same as graphs, inasmuch as they are in one-to-one correspondence with each other. However, morphisms of reflexive graphs can ‘collapse’ edges into vertices by mapping them onto distinguished loops, a possibility not permitted … Web8. aug 2024 · A graphis a collection of verticesand edges; each edgelinks a pair of vertices, defining a relationship of incidencebetween vertices and edges.
