Web6 de jan. de 2009 · Obviously, the matching polynomial can be uniquely determined by the matching generating function, and vice versa. The matching polynomial (or matching generating function) is a crucial concept in the topological theory of aromaticity [10]. The matching polynomial is also named the acyclic polynomial in [4], [6], [10]. In the mathematical fields of graph theory and combinatorics, a matching polynomial (sometimes called an acyclic polynomial) is a generating function of the numbers of matchings of various sizes in a graph. It is one of several graph polynomials studied in algebraic graph theory. how many people play osu in the usa

WebGiven a graph !!,! with vertex set ! and edge set !, a matching is a subset !⊆! such that no two edges in ! share a common vertex. A perfect matching is a matching in which every vertex of ! is met by an edge. We wish to develop a determinantial formula for the generating function of perfect matchings in a graph. 2.

WebNote. The complement option uses matching polynomials of complete graphs, which are cached. So if you are crazy enough to try computing the matching polynomial on a graph with millions of vertices, you might not want to use this option, since it will end up caching millions of polynomials of degree in the millions. WebA new approach is formulated for the matching polynomial m ( G ) of a graph G . A matrix A ( G ) is associated with G . A certain function defined on A ( G ) yields the matching polynomial of G . This approach leads to a simple characterization of m ( G ). It also facilitates a technique for constructing graphs with a given matching polynomial.
