Theorem Let G be a simple graph of order n and let ?1?,?2?,…,?n? be the eigenvalues of G. The bipartivity of G is ?(G)=?j=1n?exp(?j?)?j=1n?cosh(?j?)?.
Let G and H be the graphs shown in the next figure. Which of these graphs is closest to being bipartite? Make the corresponding calculations and argue your answer.
