Volume extrapolation via eigenvector continuation [PDF]

open access: yes, 2022
We develop an extension of eigenvector continuation (EC) that makes it possible to extrapolate simulations of quantum systems in finite periodic boxes across large ranges of box sizes.

Application of the Perturbation Method for Determination of Eigenvalues and Eigenvectors for the Assumed Static Strain

open access: yesCivil and Environmental Engineering, 2014
The paper presents the perturbation method which was used for computation of eigenvalues and eigenvectors for the assumed homogeneous state of strain in the hyperelastic Murnaghan material.

Invariant Subspaces: An Alternative for Introducing Eigenvectors and Eigenvalues

open access: yesAnnales de Didactique et de Sciences Cognitives, 2023
The concepts of eigenvalue and eigenvector are typically approached algorithmically in introductory linear algebra courses. However, a more conceptual orientation involves connecting these notions to the concept of one-dimensional invariant subspace ...

Eigenvectors of Tensors—A Primer [PDF]

open access: yesActa Applicandae Mathematicae, 2018
We give an introduction to the theory and to some applications of eigenvectors of tensors (in other words, invariant one-dimensional subspaces of homogeneous polynomial maps), including a review of some concepts that are useful for their discussion. The intent is to give practitioners an overview of fundamental notions, results and techniques.

Solving the Least Squares Method problem in the AHP for 3 X 3 and 4 X 4 matrices [PDF]

open access: yes, 2005
The Analytic Hierarchy Process (AHP) is one of the most popular methods used in Multi-Attribute Decision Making. The Eigenvector Method (EM) and some distance minimizing methods such as the Least Squares Method (LSM) are of the possible tools for ...

Galerkin eigenvector approximations [PDF]

open access: yesMathematics of Computation, 2000
How close are Galerkin eigenvectors to the best approximation available out of the trial subspace? Under a variety of conditions the Galerkin method gives an approximate eigenvector that approaches asymptotically the projection of the exact eigenvector onto the trial subspace—and this occurs more rapidly than the underlying rate of

A Globally Convergent MCA Algorithm by Generalized Eigen-Decomposition [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2011
Minor component analysis (MCA) are used in many applications such as curve and surface fitting, robust beam forming, and blind signal separation. Based on the generalized eigen-decomposition, we present a completely different approach that leads to ...
