Two graphs G and Hare isomorphic if there is an isomorphism f: V(G) → V(H) such that vertices u and v are adjacent in G if and only if f(u) and f(v) are adjacent in H. Two graphs are cospectral if the eigenvalues of the two graphs are the same. PODASIP the following statement: Two graphs are cospectral if and only if they are isomorphic.

5. Two graphs G and Hare isomorphic if there is an isomorphism ƒ: V(G) → V(H) such that vertices u and
v are adjacent in G if and only if f(u) and f(v) are adjacent in H. Two graphs are cospectral if the
eigenvalues of the two graphs are the same. PODASIP the following statement: Two graphs are
cospectral if and only if they are isomorphic.
