Remarks on inertia theorems for matrices
Remarks on inverse of matrix polynomials
Analysis of a non-classically damped engineering structure, which is subjected to an external excitation, leads to the solution of a system of second order ordinary differential equations. Although there exists a large variety of powerful numerical methods to accomplish this task, in some cases it is convenient to formulate the explicit inversion of the respective quadratic fundamental system. The presented contribution uses and extends concepts in matrix polynomial theory and proposes an implementation...

Representación finita de sistemas de infinitas inecuaciones.
Dado un Problema de Programación Semi-Infinita, si se puede obtener una representación finita del conjunto factible, pueden aplicarse para resolver el problema los métodos de programación con restricciones finitas.En la primera parte se caracterizan los sistemas lineales infinitos que pueden ser reducidos a un sistema finito equivalente, dándose además condiciones suficientes y métodos para efectuar tal reducción. En la segunda parte se establecen diferentes procedimientos de obtención de la representación...

Representations of the general linear group over symmetry classes of polynomials
Let be the complex vector space of homogeneous linear polynomials in the variables . Suppose is a subgroup of , and is an irreducible character of . Let be the symmetry class of polynomials of degree with respect to and . For any linear operator acting on , there is a (unique) induced operator acting on symmetrized decomposable polynomials by In this paper, we show that the representation of the general linear group is equivalent to the direct sum of copies of a representation...
Residual norm behavior for Hybrid LSQR regularization
Hybrid LSQR represents a powerful method for regularization of large-scale discrete inverse problems, where ill-conditioning of the model matrix and ill-posedness of the problem make the solutions seriously sensitive to the unknown noise in the data. Hybrid LSQR combines the iterative Golub-Kahan bidiagonalization with the Tikhonov regularization of the projected problem. While the behavior of the residual norm for the pure LSQR is well understood and can be used to construct a stopping criterion,...
