报告摘要A Pareto H-eigenvalue of a tensor A is a real number λ satisfying the complementarity system: 0 ≤ x(Ax  λIx) 0. The Pareto H-spectrum is the set of all Pareto H-eigenvalues. In this note, we first obtain some invariance on Pareto H-spectrum of tensors under tensor permutational similar (resp. diagonal similar) translation. As their application, we know that Pareto H-spectrum of hypergraphs is independent of the ordering of their vertices. Furthermore, we attain some nice properties on Pareto H-spectrum of hypergraphs.
