A Recursive Method for Perfect Matching Number Classified with Saturation of a Certain Vertex

    Graphical Abstract
    • Abstract
  • Two new graphs 2-2nK5 and 2-nZ5 are constructed. Using the nested recursive method, two recursive relations of the perfect matching numbers of graphs 2-2nK5 and 2-nZ5 are obtained, and then the two recursive general solutions are solved. Thus, the formula for calculating the perfect matching number of these two types of graphs is obtained.
