... 3. If G is connected, then G is bipartite iff λn = −d. Lemma 2.7. All eigenvalues of L are non-negative. Proof. Follows from Lemma 2.6 and the definition of L = D − A. For studying regular graphs, it is convenient to work with the normalized adjacency matrix M of graph G. For any d-regular graph wit ...

topological invariants of knots and links
... Moreover, these last two curves may be regarded as the diagram curves of a pair of non-interlinking knots Ki and K2 in space. If neither of the knots Ki nor K2 is unknotted we may regard Ki and K2 as factors of the composite knot K. If one of them, Ku is unknotted, the knot K must evidently be of th ...
