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. WebAbstract. In this paper we report on the properties of the matching polynomial α ( G) of a graph G. We present a number of recursion formulas for α ( G ), from which it follows that many families of orthogonal polynomials arise as matching polynomials of … how to remove jenkins in ubuntu
