On the construction of p-eigenvectors

Annales Universitatis Scientiarum Budapestinensis de Rolando Eötvös Nominatae. Sectio computatorica, 2020
Summary: Recent investigations led to the definition of \(p\)-eigenvectors: such vectors for a matrix, that the fraction of the vector norms of the matrix-vector product and the nonzero vector (as in defining a natural matrix norm) is independent of the applied \(p\)-norm. This paper elaborates this concept further, presenting general results, proof of

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.

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.

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}

An eigenvector variability plot

2009
Summary: Principal components analysis is perhaps the most widely used method for exploring multivariate data. We propose a variability plot composed of measures on the stability of each eigenvector over samples as a data exploration tool. We also show that this variability measure gives a good measure on the intersample variability of eigenvectors ...

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.
