WebIn this section, we provide the main tools to prove Theorem 1.4 and Theorem 1.5. Theorem2.1. (Rayleigh-Ritz Theorem; see [5, Theorem 4.2.2]) IfA isann×n Hermitian matrix,then ρ(A) = max x6= 0 x∗Ax x∗x. Theorem 2.1 is used to prove Theorem 1.2. The Perron-Frobenius Theorem is a very important theorem, implying that ρ = λ1 and
WebThis paper is devoted to generalized tensor eigenvalue problems. We focus on the properties and perturbations of the spectra of regular tensor pairs. Employing different techniques, we extend several classical results from matrices or matrix pairs to tensor pairs, such as the Gershgorin circle theorem, the Collatz--Wielandt formula, the Bauer--Fike theorem, the …
