correspondence A bijection between the edge sets of two graphs with this property is called a cyclic map and we see that for every graph G there exists H of

[PDF] Graph Isomorphisms - Berkeley Math

Let G = (V1,E1) and G2 = (V2,E2) be isomorphic graphs, so there is a bijection f V1 → V2 such that (a, b) ∈ E1 ⇐⇒ (f(a),f(b)) ∈ E2 Since G is bipartite, there is
