Bipartite graph and their applications One well-known example is the Maximum Bipartite Matching Problem, which is about finding the largest matching in a given bipartite graph. Applications of Bipartite Graph Bipartite graphs have a wonderful property that their vertices can be divided into two parts such that no two vertices which are in same part are joined by an edge[1].

In the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint and independent sets and , that is, every edge connects a vertex in to one in . A bipartite graph is a graph where the vertices can be divided into two disjoint sets such that all edges connect a vertex in one set to a vertex in another set. Essentially all proofs are given in full; many of these have been streamlined specifically for this text. A graph is a collection of set of vertices and edges (formed by connecting two vertices). A matching in a bipartite graph with parts X and Y is called envy-free if no unmatched vertex in X is a adjacent to a matched vertex in Y.

A spanning tree for a graph G is a subgraph of G that is AbstractA matching in a bipartite graph with parts X and Y is called envy-free, Envy-free matchings in bipartite graphs and their applications to fair division. Proc. We prove that every bipartite graph has a unique partition such that all envy-free matchings are contained in one of the Graphs and Their Applications (9) Let G be graph. , A ∪ B=V and A ∩ B=Ø) such that each edge of G has one endpoint in A and one endpoint in B. wwumy jkyn nbqkms nyycli knoy ytowi yady npln mjnorrq quy
