Signed graphs cospectral with the path

WebDec 31, 2009 · According to the graph-theoretical approach, the dynamics and statics of Gaussian chains can be expressed as a set of eigenvalues of their Laplacian matrix. As such, the existence of Laplacian cospectral trees allows the structural nonidentifiability of any branched flexible polymer. Full article WebA graph with no loops or multiple edges is called a simple graph. In figure, G 1 and G 2 are the simple graphs, but the following two graphs G 3 and G 4 are not simple graphs. Connected Graph: A graph G is connected if each pair of vertices in G belongs to a path; otherwise, G is disconnected. In figure, G 1 is connected, but G 2 is disconnected.
