报告摘要：Let G be an even uniform connected hypergraph with cut vertices. Then G is the coalescence of two connected sub-hypergraphs both called the branches of G.. Let A(G), Q(G) be the adjacency tensor and signless Laplacian tensor of G respectively. The least H-eigenvalue of A(G) or Q(G) refers the least real eigenvalue of A(G) or Q(G) associated with real eigenvectors. We study how the least H-eigenvalue of A(G) or Q(G) perturbs when one branch is relocated from one vertex to another vertex, and generalize some results for simple graphs.
