Some spectral properties of uniform hypergraphs
TL;DR: Some spectral characterizations of odd-bipartite hypergraphs are given, and a partial answer to a question posed by Shao et al (2014) is given.
Journal ArticleDOI
Some spectral properties of uniform hypergraphs
TL;DR: In this article, the Laplacian tensor tensor of a regular hypergraph is derived from the spectrum of the degree sequence of the hypergraph, and the spectral properties of power hypergraphs are studied.
Journal ArticleDOI
Some results on resistance distances and resistance matrices
TL;DR: In this paper, an application of resistance distances to the bipartiteness of graphs is given, and an interlacing inequality for eigenvalues of the resistance matrix and the Laplacian matrix is given.
Journal ArticleDOI
The inverse, rank and product of tensors
TL;DR: In this paper, the rank of a uniform hypergraph is independent of the ordering of its vertices and the Laplacian tensor has the same rank for odd-bipartite even-uniform hypergraphs.
