چکیده

Let G be a graph embedded in surface and let the set of all faces G. For given subset $$\mathcal F$$ even (faces bounded by an cycle), resonance with respect to $${\mathcal {F}}$$ , denoted $$R(G;\mathcal F)$$ is such that its vertex perfect matchings two vertices $$M_1$$ $$M_2$$ are adjacent if only symmetric difference $$M_1\oplus M_2$$ cycle bounding some face . It has been shown plane elementary bipartite graph, inner isomorphic covering distributive lattice. However, this result does not hold general for graphs The structure properties remain unknown. In paper, we show every connected component on even-face can always into hypercube as induced subgraph. Further, Clar polynomial equal cube $$R(G;{\mathcal {F}})$$

Resonance Graphs and Perfect Matchings of Graphs on Surfaces

Let G be a graph embedded in a surface and let F be a set of even faces of G (faces bounded by a cycle of even length). The resonance graph of G with respect to F, denoted by R(G;F), is a graph such that its vertex set is the set of all perfect matchings of G and two vertices M1 and M2 are adjacent to each other if and only if the symmetric difference M1 ⊕M2 is a cycle bounding some face in F. ...

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...

On Perfect Matchings in Matching Covered Graphs

Let G be a matching-covered graph, i.e., every edge is contained in a perfect matching. An edge subsetX ofG is feasible if there exists two perfect matchingsM1 andM2 such that |M1∩X| 6≡ |M2∩X| (mod 2). Lukot’ka and Rollová proved that an edge subset X of a regular bipartite graph is not feasible if and only if X is switching-equivalent to ∅, and they further ask whether a non-feasible set of a ...

On Counting Perfect Matchings in General Graphs

Counting perfect matchings has played a central role in the theory of counting problems. The permanent, corresponding to bipartite graphs, was shown to be #P-complete to compute exactly by Valiant (1979), and a fully polynomial randomized approximation scheme (FPRAS) was presented by Jerrum, Sinclair, and Vigoda (2004) using a Markov chain Monte Carlo (MCMC) approach. However, it has remained a...

Perfect Matchings of Cellular Graphs

We introduce a family of graphs, called cellular, and consider the problem of enumerating their perfect matchings. We prove that the number of perfect matchings of a cellular graph equals a power of 2 tiroes the number of perfect matchings of a certain subgraph, called the core of the graph. This yields, as a special case, a new proof of the fact that the Aztec diamond graph of order n introduc...
