An improved linear bound on the number of perfect matchings in cubic graphs

چکیده
We show that every cubic bridgeless graph with n vertices has at least 3n/4 − 10 perfect matchings. This is the first bound that differs by more than a constant from the maximal dimension of the perfect matching polytope.

Perfect Matchings in Edge-Transitive Graphs
We find recursive formulae for the number of perfect matchings in a graph G by splitting G into subgraphs H and Q. We use these formulas to count perfect matching of P hypercube Qn. We also apply our formulas to prove that the number of perfect matching in an edge-transitive graph is , where denotes the number of perfect matchings in G, is the graph constructed from by deleting edges with an en...
متن کاملA superlinear bound on the number of perfect matchings in cubic bridgeless graphs
Lovász and Plummer conjectured in the 1970’s that cubic bridgeless graphs have exponentially many perfect matchings. This conjecture has been verified for bipartite graphs by Voorhoeve in 1979, and for planar graphs by Chudnovsky and Seymour in 2008, but in general only linear bounds are known. In this paper, we provide the first superlinear bound in the general case.
متن کاملA New Lower Bound on the Number of Perfect Matchings in Cubic Graphs
We prove that every n-vertex cubic bridgeless graph has at least n/2 perfect matchings and give a list of all 17 such graphs that have less than n/2 + 2 perfect matchings.
متن کاملCoverings, matchings and paired domination in fuzzy graphs using strong arcs
The concepts of covering and matching in fuzzy graphs using strong arcs are introduced and obtained the relationship between them analogous to Gallai’s results in graphs. The notion of paired domination in fuzzy graphs using strong arcs is also studied. The strong paired domination number γspr of complete fuzzy graph and complete bipartite fuzzy graph is determined and obtained bounds for the s...
متن کاملA bound on the number of perfect matchings in Klee-graphs
We focus on a specific class of planar cubic bridgeless graphs, namely the klee-graphs. K4 is the smallest klee-graph and having a klee-graph G we create another klee-graph by replacing any vertex of G by a triangle, i.e., applying Y∆ operation. In this paper, we prove that every klee-graph with n ≥ 8 vertices has at least 3 · 2 perfect matchings, improving the 2 bound inherited from the genera...
