An improved eigenvector beamformer

ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Most techniques for computing beamformer tap weights do so by maximizing the overall signal-to-noise ratio at the system output, where noise includes both thermal noise and directional interference. This is the optimal solution if the two noise sources count equally.

Eigenvalues and eigenvectors

2007
Eigenvalues and the associated eigenvectors of an endomorphism of a vector space are defined and studied, as is the spectrum of an endomorphism. The characteristic polynomial of a matrix is considered and used to define the characteristic polynomial of the endomorphism of a finitely-generated vector space.

Node and Layer Eigenvector Centralities for Multiplex Networks [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2018
Eigenvector-based centrality measures are among the most popular centrality measures in network science. The underlying idea is intuitive and the mathematical description is extremely simple in the framework of standard, mono-layer networks.

Eigenvectors of a Raman Medium

Physical Review Letters, 2000
We show the existence of discrete sets of Raman sidebands which self-consistently establish a Raman coherence and propagate without change in amplitude and relative phase. Equivalently, there exist periodic femtosecond-time-scale, temporal pulse shapes which propagate without change in shape.

ON RIGHT AND LEFT EIGENVECTORS

JP Journal of Algebra, Number Theory and Applications, 2019
Summary: In this paper, we show that if \(\lambda\) is an eigenvalue of a square matrix \(\mathcal{A}\), then by using the largest non-singular sub-matrix of the matrix \(\mathcal{A}_\lambda=\mathcal{A}-\lambda\mathcal{I}\), we may obtain all the linearly independent right and left eigenvectors of \(\mathcal{A}\), corresponding to the eigenvalue ...

Derivatives and Perturbations of Eigenvectors

SIAM Journal on Numerical Analysis, 1988
Es sei \(D\subset {\mathbb{C}}\) ein Gebiet, A(z) sei eine \(n\times n\)-Matrix, deren Elemente auf D definierte Funktionen von z sind, und x(z), y(z) seien n-dimensionale Vektorfelder auf D, wobei x(z) speziell Eigenvektor von A(z) zum Eigenwert \(\lambda\) (z) sei. Schließlich bedeute \(\sigma\) : \({\mathbb{C}}^ n\times {\mathbb{C}}^ n\to {\mathbb{C}

The Parallel Eigenvectors Operator

2018
The parallel vectors operator is a prominent tool in visualization that has been used for line feature extraction in a variety of applications such as ridge and valley lines, separation and attachment lines, and vortex core lines. It yields all points in a 3D domain where two vector fields are parallel.

Pei matrix eigenvectors

Communications of the ACM, 1963
M. L. Pei [ Comm. ACM 5 , 10 (Oct. 1962)] gave an explicit inverse for a matrix of the form M + δI , where M is an n -square matrix of ones and δ is a nonzero parameter.
