摘要
具有r个悬挂点的树是r叶树.本文研究了具有n个顶点4叶树的Merrifield-Simmons指标,刻画了18Fn-6+21Fn-7≤σ(T)≤117Fn-9+39Fn-11的4叶树及其σ-指标序列.
A Tree Tis called a r-leaf-tree if Thas rpendent vertices.In this paper,we studied Merrifield-Simmons index of 4-leaf-tree with order nand depicting the leaves of the tree 18F n-6 ＋21F n-7 ≤ σ（T） ≤117F n-9 ＋39F n-11 and its index order.
