On characteristic invariants of matrix pencils and linear relations
Hannes Gernandt, Francisco Martínez Pería, Friedrich Philipp +1
The relationship between linear relations and matrix pencils is investigated. Given a linear relation, we introduce its Weyr characteristic. If the linear relation is the range (or…
Indefinite least squares with a quadratic constraint
Santiago Gonzalez Zerbo, Alejandra Maestripieri, Francisco Martínez Pería
An abstract indefinite least squares problem with a quadratic constraint is considered. This is a quadratic programming problem with one quadratic equality constraint, where neithe…
Linear pencils and quadratic programming problems with a quadratic constraint
Santiago Gonzalez Zerbo, Alejandra Maestripieri, Francisco Martínez Pería
Given bounded selfadjoint operators and acting on a Hilbert space , consider the linear pencil , . The set of parameters such th…
