A polynomial eigenvalue approach for multiplex networks [PDF]

open access: yesNew Journal of Physics, 2018
We explore the block nature of the matrix representation of multiplex networks, introducing a new formalism to deal with its spectral properties as a function of the inter-layer coupling parameter.

Hermitian separability of BFKL eigenvalue in Bethe–Salpeter approach

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We consider the Bethe–Salpeter approach to the BFKL evolution in order to naturally incorporate the property of the Hermitian separability in the BFKL approach.

Eigenvalue enclosures and exclosures for non-self-adjoint problems in hydrodynamics [PDF]

open access: yes, 2010
In this paper we present computer-assisted proofs of a number of results in theoretical fluid dynamics and in quantum mechanics. An algorithm based on interval arithmetic yields provably correct eigenvalue enclosures and exclosures for non-self-adjoint ...

Principal eigenvalue problem for infinity Laplacian in metric spaces

open access: yesAdvanced Nonlinear Studies, 2022
This article is concerned with the Dirichlet eigenvalue problem associated with the ∞\infty -Laplacian in metric spaces. We establish a direct partial differential equation approach to find the principal eigenvalue and eigenfunctions in a proper geodesic

Generalized eigenvalue approach for dynamic mode decomposition

open access: yesAIP Advances, 2021
Traditional dynamic mode decomposition (DMD) methods inevitably involve matrix inversion, which often brings in numerical instability and spurious modes.

Angle of arrival estimation for broadband signals : a comparison [PDF]

open access: yes, 2013
This paper reviews and compares three different linear algebraic signal subspace techniques for angle of arrival estimation. These include a polynomial matrix approach to multiple signal classification (MUSIC), a parameterised spatial covariance matrix ...

Hybridized Ackermann’s Methods

open access: yesIEEE Access, 2022
Further elaborations on the modified Ackermann’s method (MAM) for eigenvalue assignment are considered in this paper. Additional results concerning the incomplete eigenvalue assignment (IEA) are stated, verified, and commented.

An Iterative Approach to Eigenvalue Assignment for Nonlinear Systems. [PDF]

open access: yesProceedings of the 45th IEEE Conference on Decision and Control, 2006
In this paper, the authors present a method for controlling a nonlinear system by using the ideas of eigenvalues assignment. A time-varying approach to nonlinear exponential stability via eigenvalue placement is studied based on an iteration technique that approaches a nonlinear system by a sequence of linear time varying equations.

Vibrational analysis of an irregular single-walled carbon nanotube incorporating initial stress effects

open access: yesNanotechnology Reviews, 2020
In this work, an attempt is done to apply the eigenvalue approach as well as Donnell thin-shell theory to find out the vibrational analyses of an irregular single-walled carbon (ISWCNT) incorporating initial stress effects.
