Connected matchings in chordal bipartite graphs
A connected matching in a graph is a collection of edges that are pairwise disjoint but joined by another edge of the graph. Motivated by applications to Hadwiger’s conjecture, Plummer, Stiebitz, and Toft [13] introduced connected matchings and proved that, given a positive integer k, determining whether a graph has a connected matching of size at least k is NPcomplete. Cameron [4] proved that ...
متن کاملInduced matchings in bipartite graphs
All graphs in this paper are understood to be finite, undirected, without loops or multiple edges. The graph G' = (V', E') is called an induced subgraph of G = (V, E) if V' ~ V and uv E E' if and only if {u, v} ~ V', uv E E. The following two problems about induced matchings have been formulated by Erdos and Nesetril at a seminar in Prague at the end of 1985: 1. Determine f(k, d), the maximum n...
متن کاملRecognizing Chordal-Bipartite Probe Graphs
A graph G is chordal-bipartite probe if its vertices can be partitioned into two sets P (probes) and N (non-probes) where N is a stable set and such thatG can be extended to a chordal-bipartite graph by adding edges between non-probes. A bipartite graph is called chordal-bipartite if it contains no chordless cycle of length strictly greater than 5. Such probe/non-probe completion problems have ...
متن کاملTreewidth of Chordal Bipartite Graphs
Chordal bipartite graph are exactly those bipartite graph in which every cycle of length at least six has a chord. The treewidth of a graph G is the smallest maximum cliquesize among all chordal supergraphs of G decreased by one. We present a polynomial time algorithm for the exact computation of the treewidth of all chordal bipartite graphs. keywords: Graph algorithms, Algorithms and Data Stru...
متن کاملBipartite Graphs and Perfect Matchings
When we think about markets creating opportunities for interaction between buyers and sellers, there is an implicit network encoding the access between buyers and sellers. In fact, there are several ways to use networks to model buyer-seller interaction, and here we discuss some of them. First, consider the case in which not all buyers have access to all sellers. There could be several reasons ...
