Free Vibrations of Multi-Degree Structures: Solving Quadratic Eigenvalue Problems with an Excitation and Fast Iterative Detection Method

open access: yesVibration, 2022
For the free vibrations of multi-degree mechanical structures appeared in structural dynamics, we solve the quadratic eigenvalue problem either by linearizing it to a generalized eigenvalue problem or directly treating it by developing the iterative ...

Grouped variable selection for generalized eigenvalue problems [PDF]

open access: yesSignal Processing, 2022
Many problems require the selection of a subset of variables from a full set of optimization variables. The computational complexity of an exhaustive search over all possible subsets of variables is, however, prohibitively expensive, necessitating more efficient but potentially suboptimal search strategies.

A generalized Fucik type eigenvalue problem for p-Laplacian

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
In this paper we study the generalized Fucik type eigenvalue for the boundary value problem of one dimensional $p-$Laplace type differential equations \[ \left\{\begin{array}{lll} - (\varphi( u')) ' = \psi(u), \quad -T< x < T; \\ \quad u(-T)=0, \quad u ...

Left and right inverse eigenpairs problem with a submatrix constraint for the generalized centrosymmetric matrix

open access: yesOpen Mathematics, 2020
Left and right inverse eigenpairs problem is a special inverse eigenvalue problem. There are many meaningful results about this problem. However, few authors have considered the left and right inverse eigenpairs problem with a submatrix constraint.

Eigenvalue and Generalized Eigenvalue Problems: Tutorial

open access: yesCoRR, 2019
This paper is a tutorial for eigenvalue and generalized eigenvalue problems. We first introduce eigenvalue problem, eigen-decomposition (spectral decomposition), and generalized eigenvalue problem. Then, we mention the optimization problems which yield to the eigenvalue and generalized eigenvalue problems. We also provide examples from machine learning,

Computation of interior elastic transmission eigenvalues using a conforming finite element and the secant method

open access: yesResults in Applied Mathematics, 2020
The interior elastic transmission eigenvalue problem, arising from the inverse scattering theory of non-homogeneous elastic media, is nonlinear, non-self-adjoint and of fourth order.

Least Squares Problems with Absolute Quadratic Constraints

open access: yesJournal of Applied Mathematics, 2012
This paper analyzes linear least squares problems with absolute quadratic constraints. We develop a generalized theory following Bookstein's conic-fitting and Fitzgibbon's direct ellipse-specific fitting.
