Webrank approximation, specifically the Ecart-Young-Mirsky theorem. We looked at the Rayleigh-Ritz theorem and the Courant-Fischer (Min-max) theorem. Finally, we showed trace maximization and minimization. 2 Matrix Norms 2.1 Matrix p-norm We start by defining the basic building block of the matrix p-norm: Definition 1 (Vector p-norm).

WebMar 1, 2024 · The trajectory boundedness of the spacecraft between adjacent impulses are analyzed using the Gerschgorin and the Rayleigh-Ritz theorems as well as a finite form of the Jensen's inequality. Some boundaries are introduced regarding the Jordan-Brouwer separation theorem which are useful in checking the satisfaction of a constraint. WebMar 24, 2024 · This paper studies global stability properties of the Rayleigh–Ritz approximation of eigenvalues of the Laplace operator. The focus lies on the ratios $$\\hat{\\lambda }_k/\\lambda _k$$ λ ^ k / λ k of the kth numerical eigenvalue $$\\hat{\\lambda }_k$$ λ ^ k and the kth exact eigenvalue $$\\lambda _k$$ λ k . In the … 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 … list of all the gods and goddesses
