Optimal Control Applications and Methods, Volume 46, Issue 4, Page 1538-1558, July/August 2025.This article introduces a novel sensitivity‐based algorithm for nonlinear distributed model predictive control. The algorithm requires only local computations with one neighbor‐to‐neighbor communication step per iteration and exhibits a linear order of convergence under suitable conditions.

Inverse eigenvalue problems for Jacobi matrices
Linear Algebra and its Applications, 1976 AbstractIt is proved that a real symmetric tridiagonal matrix with positive codiagonal elements is uniquely determined by its eigenvalues and the eigenvalues of the largest leading principal submatrix, and can be constructed from these data. The matrix depends continuously on the data, but because of rounding errors the investigated algorithm might in ...

Scale‐dependent variation in leaf functional traits clarifies mechanisms of invasion
Ecography, Volume 2025, Issue 7, July 2025.Comparing the functional traits of co‐occurring native and invasive plant species can offer insight regarding mechanisms of invasion. Previous studies have failed to reach a consensus, indicating that the extent of trait differences between native and invasives might depend on the environmental context and on the spatial grain of the analysis.

Approximation of eigenvalues of some unbounded self-adjoint discrete Jacobi matrices by eigenvalues of finite submatrices [PDF]
Opuscula Mathematica, 2007 We investigate the problem of approximation of eigenvalues of some self-adjoint operator in the Hilbert space \(l^2(\mathbb{N})\) by eigenvalues of suitably chosen principal finite submatrices of an infinite Jacobi matrix that defines the operator ...

The role of target populations in resident support for local collaboration
Public Administration Review, Volume 85, Issue 4, Page 1115-1133, July/August 2025.Abstract The characteristics of populations benefiting from collaboration are mostly regarded as contextual factors in collaborative theory and research. Drawing on policy design and distributive justice theories, this study seeks to understand how public support for collaboration varies depending on the characteristics of the target population that ...

A Jacobi Generalized Orthogonal Joint Diagonalization Algorithm for Joint Blind Source Separation
IEEE Access, 2018 Joint blind source separation (J-BSS) has emerged as a data-driven technique for multi-set data fusion applications. In this paper, we propose a Jacobi generalized orthogonal joint diagonalization (GOJD) algorithm for J-BSS of multiset signals.

Continued fractions and periodic jacobi matrices
Linear Algebra and its Applications, 1992 AbstractWe describe an algorithm, based on a continued fraction expansion, to reconstruct a periodic Jacobi matrix from spectral data. We also compare various different sets of spectral data which characterize a periodic Jacobi matrix.

Special functions and spectrum of Jacobi matrices
Linear Algebra and its Applications, 2015 Several examples of Jacobi matrices with an explicitly solvable spectral problem are worked out in detail. In all discussed cases the spectrum is discrete and coincides with the set of zeros of a special function. Moreover, the components of corresponding eigenvectors are expressible in terms of special functions as well.

Multipreconditioned GMRES for simulating stochastic automata networks
Open Mathematics, 2018 Stochastic Automata Networks (SANs) have a large amount of applications in modelling queueing systems and communication systems. To find the steady state probability distribution of the SANs, it often needs to solve linear systems which involve their ...
