摘要
本文应用计算生成树个数的有向图方法、分块矩阵的行列式计算法以及常系数线性递归方程的解法 ,计算得到轮图和多轮图的生成树个数的表达式 (显式或递推式 )
In this paper, expressions (explicit expression and recursion expression) of spanning tree numbers of wheelgraph and multiwheelgraph are obtained through calculating spanning tree numbers with digraph method, calculating block matrix determinant and solving constant coefficient linear recurring equation.
