WebOne obtains for this algebraic connectivity, the long exact sequences, relative [co]homologies, and the analogues of the usual [co]homological notions of the algebraic topologists. In fact, we show that the [co]homologies are actually the same as the simplicial [co]homology of simplicial complexes that depend functorially on the algebras. WebThe Laplacian, especially Lemma 2.3.1 (Graph connectivity). Please, help me to make it a little bit clearer. Lemma 2.3.1. Let be a graph, and let be the eigenvalues of its Laplacian matrix.
