Positive bidiagonal factorization of tetradiagonal Hessenberg matrices

open access: yes, 2022
Recently a spectral Favard theorem for bounded banded lower Hessenberg matrices that admit a positive bidiagonal factorization was presented. In this paper conditions, in terms of continued fractions, for an oscillatory tetradiagonal Hessenberg matrix to

Bidiagonal factorization of tetradiagonal matrices and Darboux transformations

open access: yes, 2022
Recently a spectral Favard theorem for bounded banded lower Hessenberg matrices that admit a positive bidiagonal factorization was presented. These type of matrices are oscillatory.

Canonical triangulations of Dehn fillings [PDF]

open access: yes, 2010
Every cusped, finite-volume hyperbolic three-manifold has a canonical decomposition into ideal polyhedra. We study the canonical decomposition of the hyperbolic manifold obtained by filling some (but not all) of the cusps with solid tori: in a broad ...

Negative integral powers of a bidiagonal matrix

open access: yes, 1974
The elements of the inverse of a bidiagonal matrix have been expressed in a convenient form. The higher negative integral powers of the bidiagonal matrix exhibit an interesting property: the (ij)th element of the ( − m )

SINGULAR RANDOM MATRIX DECOMPOSITIONS: DISTRIBUTIONS. [PDF]

open access: yes
Assuming that Y has a singular matrix variate elliptically contoured distribution with respect to the Hausdorff measure, the distributions of several matrices associated to QR, modified QR, SV and Polar decompositions of matrix Y are determined, for ...

Spectra, pseudospectra, and localization for random bidiagonal matrices [PDF]

open access: yes, 2000
There has been much recent interest, initiated by work of the physicists Hatano and Nelson, in the eigenvalues of certain random non-hermitian periodic tridiagonal matrices and their bidiagonal limits. These eigenvalues cluster along a "bubble with wings"

Bidiagonal Factorization

open access: yes, 2011
This chapter introduces and methodically develops the important and useful topic of bidiagonal factorization. Factorization of matrices is one of the most important topics in matrix theory, and plays a central role in many related applied areas such as ...

Subgroup and Shapely Value Decompositions of Multidimensional Inequality: An Application to South East European Countries [PDF]

open access: yes
Inequality is a multidimensional phenomenon though it is often discussed along a single dimension like income. This is also the case for the various decomposition approaches of inequality indices.
