报告摘要:
In this talk, we report some results on the Laplacian subtensors and principle eigenvector of uniform hypergraphs. Relations between mininum eigenvalues of Laplacian subtensors and connectivity of uniform hypergraphs are discussed. We also give some bounds on principle eigenvector and spectral radius of uniform hypergraphs via degrees, diameter and the number of vertices.
