http://cmsc-27100.cs.uchicago.edu/2024-winter/Lectures/26/ WebGraph isomorphism is an equivalence relation on graphs and as such it partitions the class of all graphs into equivalence classes. A set of graphs isomorphic to each other is called an isomorphism class of graphs. Webization problem for graphs is to produce a canonical form canon(G) for a given graph G such that canon(G) is isomorphic to Gand canon(G1) = canon(G2) for any pair of iso-morphic graphs G1 and G2.

If we go down this path, we would have to show that every bijection fails to preserve adjacency. The advantage of the checklist is that it will give you a quick and easy way to show two graphs are not isomorphic if some invariant of the graphs turn out to be di erent. can a gradient be negative

"WebHowever, this task is nontrivial, since most of the previous settings for graph isomorphism are only applicable to 2D topological features. For 3D geometric shapes, we should take the SE(3) symme-try into account. Formally, two 3D geometric graphs X,Y are deﬁned to be globally isomorphic, if there exists g ∈SE(3) such that Y = gX.
