WebFeb 5, 2024 · The set T ( Y) is called tree. Definition 3. A tree isomorphism is a bijection between the vertices that preservers the adjacent vertices. If X and Y finite sets such that X = Y , then is easy to see that the trees T ( X) and T ( Y) are isomorphism.

When graphs G and H are isomorphic they have the same chromatic number, if one has an Eulerian or Hamiltonian circuit so does the other, if G is planar so is H, if one is connected so is the other. If one has drawings of the two graphs, our visual systems are so attuned ...
