El OBJETIVO es aprender qué es la factorización de matrices no negativa y cómo funciona el algoritmo basado en la minimización de la distancia de Frobenius (Algoritmo Lee Seung o algoritmo multiplicativo).
La factorización ...

La factorización de matrices no negativa consiste en la descomposición de una matriz cuyos elementos son no negativos en el producto de dos matrices también no negativas. Presentamos una aplicación muy importante: la ...
[EN] We present a vector valued duality between factorable (q,p)-summing polynomials and (q,p)-summing linear operators on symmetric tensor products of Banach spaces. Several applications are provided. First, we prove a ...
In this paper we study the ideal of dominated
(p,s)-continuous polynomials, that extend
the nowadays well known ideal of
p-dominated polynomials to the more general setting
of the interpolated ideals of polynomials. ...
[EN] Let (X,d) be a pointed metric space. Let T : X ¿ Y1(µ) and S : X ¿ Y2(µ) be two Lipschitz operators into two Banach function spaces Y1 and Y2 over the same finite measure µ. We show which are the vector norm inequalities ...

[EN] We study factorization of operators between quasi-Banach spaces. We prove the equivalence between certain vector norm inequalities and the factorization of operators through Orlicz spaces. As a consequence, we obtain ...

[EN] We analyze domination properties and factorization of operators in Banach spaces through subspaces of L1-spaces. Using vector measure integration and extending classical arguments based on scalar integral bounds, we ...

We introduce the new ideal of strongly-continuous linear operators in order to study the adjoints of the -absolutely continuous linear operators. Starting from this ideal we build a new multi-ideal by using the composition ...

[EN] In this note we show that weakly compact operators from a Banach space X into
a complete (LB)-space E need not factorize through a reflexive Banach space. If E is a Fréchet space, then weakly compact operators from ...
[EN] In this paper, we characterize compact linear operators from
Banach function spaces to Banach spaces by means of approximations
with bounded homogeneous maps. To do so, we undertake a detailed
study of such maps, ...
[EN] Let X Y and Z be Banach function spaces over a measure space . Consider the spaces of multiplication operators from X into the Kothe dual Y' of Y, and the spaces X (Z) and defined in the same way. In this paper we ...

[EN] Two new classes of summing multilinear operators, factorable (q,p)-summing operators and (r;p,q)-summing operators are studied. These classes are described in terms of factorization. It is shown that operators in the ...
[EN] We show a factorization through Lorentz spaces for Banach-space-valued operators defined in Banach function spaces. Although our results are inspired in the classical factorization theorem for operators from Ls-spaces ...
[EN] We investigate the factorized solution of generalized stable Sylvester equations such as those arising in model reduction, image restoration, and observer design. Our algorithms, based on the matrix sign function, ...
Consider an operator T : X--->Y between Banach function
spaces having adequate order continuity and Fatou properties.
Assume that T can be factorized through a Banach space as T =SR,
where R and the adjoint of S are ...

[EN] Anatomically based procedures to ablate atrial fibrillation (AF) are often successful in terminating paroxysmal AF. However, the ability to terminate persistent AF remains disappointing. New mechanistic approaches use ...
