超树的正负惯性指数
Positive and negative inertia index of a hypertree
摘要
Abstract
This paper extend the conclusion of the graph to hypergraphs,prove that the positive and negative inertia index of a single hypertree are related to the number of hyperedges and vertices,and give the positive and negative inertia index of two hypertrees connected by a hyperedge.关键词
