For example, although graphs A and … WebJun 22, 2015 · In simple terms, two graphs are isomorphic to each other so long as there is a bijection between the two vertex sets and such that the bijection preserves edges. That is, two graphs G and G ′ are isomorphic if there exists a bijection, ϕ: V ( G) → V ( G ′), and if that bijection also preserves edges.

WebJun 16, 2024 · Intuitively, every permutation of those six vertices that preserves the "red-blue" partition is an isomorphism of the graph: you can permute the red vertices amongst themselves and the blue vertices amongst them selves, and you can also turn the whole graph upside down, swapping the red vertex set and the blue vertex set. Die Isomorphie von Graphen (oder Graphenisomorphie) ist in der Graphentheorie die Eigenschaft zweier Graphen, strukturell gleich zu sein. Bei der Untersuchung graphentheoretischer Probleme kommt es meist nur auf die Struktur der Graphen, nicht aber auf die Bezeichnung ihrer Knoten an.
