WebIf we take the cospectral graphs K1,4 and C4 + K1 and attach the path Pn to each vertex in these graphs, then the resulting graphs, one of them S (n, n, n, n, n − 1), are still cospectral. All known graphs cospectral with starlike trees have a component which is a path. This has motivated us to establish a set of necessary and sufficient ... WebSigned graphs of small order . Every edge of a signed graph is accompained by the sign + or -. Signed graphs may be encountered in domains of social psychology, physics, chemistry, control theory, social or other complex networks, etc. Simple (i.e., 'unsigned') graphs are recognized as particular cases of signed graphs with all edges being of the same sign; …
