Web20 de jun. de 2024 · In this paper, we devote to studying the distribution of zeros of the matching polynomials of -graphs. We prove that the zeros (with multiplicities) of $\mu (\h, x)$ are invariant under a rotation of an angle in the complex plane for some positive integer and is the maximum integer with this property. Let $\lambda (\h)$ denote the maximum ... Web2.2 Matching polynomial In 1972, Heilman and Lieb [27] first used a polynomial for the theory of monomer–dimer systems without determining its specific name. In 1979, Farrell [28] denominated it as the matching polynomial, which is made up of collecting k-matching numbers of independent edges in a graph. So far,
