The simple graphs G? = (V?,E?) and G? = (V?,E?) are isomorphic if there exists a one-to-one and onto function f from V? to V? with the property that a and b are adjacent in G? if and only if f (a) and f (b) are adjacent in G?, for all a and b in V?. Use this definition (or other techniques) to show that the following pairs of graphs are isomorphic or not isomorphic. a. b.

Step 1
This includes the number of vertices, the number of edges, and the degree sequence. a. Since no graphs are mentioned, it is not possible to determine if they are isomorphic or not. Show more…
