WebNov 11, 2024 · A graph morphism is a pair of maps between the respective set of vertices p: V → V and and between the respective set of edges q: E → E. If I set q ( e) = f, q ( f) = e and q ( l) = l then because of the adjacency relation, I have to set: w = initial vertex of f = initial vertex of q ( e) = p ( initial vertex of e) = p ( v). WebTo show that the two graphs are isomorphic, apply the given definition. Let's call the graph on the left G [ V 1, E 1], and the graph on the right G [ V 2, E 2]. Now give an explicit bijection f: V 1 V 2, and show that if { e 1, e 2 } ∈ E 1, then { f ( e 1), f ( e 2) } ∈ E 2.
