bipartite graph definition in graph theory

What is a bipartite graph?
The bipartite structure allows for a natural way to match vertices from one set to vertices in the other set. Social networks: Bipartite graphs, where the nodes in one set represent users and the nodes in the other set reflect interests, groups, or communities, can be used to simulate social networks.
What is the adjacency matrix of a complete bipartite graph?
The complete bipartite graph Km,n has a vertex covering number of min{m, n} and an edge covering number of max{m, n}. The complete bipartite graph Km,n has a maximum independent set of size max{m, n}. The adjacency matrix of a complete bipartite graph Km,n has eigenvalues √nm, −√nm and 0; with multiplicity 1, 1 and n + m − 2 respectively.
What is a k-partite graph?
A k-partite graph is a graph that may be partitioned into k sets such that no vertex in any of the k sets connects to another element of that same set. We can generalize the previous theorem by saying that every k-partite graph is k-colorable and the proof is similar to the proof for two.
What if v1 v2 is adjacent to vertices in a bipartite graph?
If v ∈ V2 then it may only be adjacent to vertices in V1. V1 ∪ V2 = V (G) We can imagine bipartite graphs to look like two parallel lines of vertices such that a vertex in one line can only connect to vertices in the other line, and not to vertices in its own line.
