What is the spectrum of a bipartite graph?
It turns out that bipartite graphs can be characterized by the spectrum of their adjacency matrix. The following lemma says that the spectrum of a bipartite graph must be symmetric around the origin on the real line. eigenvalue of A(G) with multiplicity k, then ?? is an eigenvalue of A(G) with multiplicity k. BT 0 ) .Are bipartite graphs 3 Colourable?
A graph is bipartite if and only if it is 2-colorable, (i.e. its chromatic number is less than or equal to 2).What is the chromatic number of a complete bipartite graph?
For a simple bipartite graph, when every vertex in A is joined to every vertex in B, and vice versa, the graph is called a complete bipartite graph.
