WebMar 24, 2024 · A perfect matching of a graph is a matching (i.e., an independent edge set) in which every vertex of the graph is incident to exactly one edge of the matching. A perfect matching is therefore a … In the mathematical discipline of graph theory, a matching or independent edge set in an undirected graph is a set of edges without common vertices. In other words, a subset of the edges is a matching if each vertex appears in at most one edge of that matching. Finding a matching in a bipartite graph can be treated … See more Given a graph G = (V, E), a matching M in G is a set of pairwise non-adjacent edges, none of which are loops; that is, no two edges share common vertices.

WebJul 15, 2024 · 1 Answer. This is false for k = 3. If you remove a perfect matching from a 3 -regular graph, the result is a union of cycles; the only way this could be connected is if it's a Hamiltonian cycle. The Horton graph is an example of a 3 -regular bipartite graph that does not have a Hamiltonian cycle.
