Cored Hypergraphs, Power Hypergraphs and Their Laplacian H-Eigenvalues
Shenglong Hu, Liqun Qi, Jia-Yu Shao
In this paper, we introduce the class of cored hypergraphs and power hypergraphs, and investigate the properties of their Laplacian H-eigenvalues. From an ordinary graph, one may g…

Symmetric Nonnegative Tensors and Copositive Tensors
Liqun Qi
We first prove two new spectral properties for symmetric nonnegative tensors. We prove a maximum property for the largest H-eigenvalue of a symmetric nonnegative tensor, and establ…

E-Characteristic Polynomials of Tensors
An-Min Li, Liqun Qi, Bin Zhang
In this paper, we show that the coefficients of the E-characteristic polynomial of a tensor are orthonormal invariants of that tensor. When the dimension is 2, some simplified form…
