... cycles of G ′ containing every edge of the form e P . By enumerating all Hamilton cycles of G ′ and ignoring those which do not contain every edge of the form e P we obtain a list of all the electronic ... 7 Enumerating all Hamilton Cycles and Bounding the Number of Hamilton Cycles in 3-Regular Graphs ∗ Heidi Gebauer Institute of Theoretic...

... of interest. First, they are derived from a mere knowledge of the degrees of the vertices involved in the perturbation. Second, they are the best possible, in the sense that we characterize the cases ... eigenvalues in the complex plane. The spectral radius is the maximum of the modulus of its eigenvalues. If the matrix is the adjacency matrix of a gr...
