Signed graphs cospectral with the path
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.
