Coincidence of extendible vector-valued ideals with their minimal kernel
(Elsevier Inc, 2015-01)
We provide coincidence results for vector-valued ideals of multilinear operators. More precisely, if A is an ideal of n-linear mappings we give conditions for which the equality A(E1, ..., En; F) = Amin(E1, ..., En; F) ...
Operator ideals and assembly maps in K-theory
(American Mathematical Society, 2013-12)
Let B be the ring of bounded operators in a complex, separable Hilbert space. For p > 0 consider the Schatten ideal Lp consisting of those operators whose sequence of singular values is p-summable; put S = S p Lp. Let G ...
Herdeiros do idealismo Alemão
(Universidade Estadual Paulista (Unesp), Departamento de Filosofia, 1994-01-01)
Acompanha-se, aqui, a pertinência do lema de Engels, que concebe o marxismo como herdeiro do idealismo alemão nas teorias de Lukács, Horkheimer e Adorno. Enquanto Lukács assenta o método marxista na vertente da filosofia ...

Maximal ideals and representations of twisted forms of algebras
(Mathematical Sciences Publishers, 2013-07)
Abstract Given a central simple algebra g g and a Galois extension of base rings S ∕ R S∕R, we show that the maximal ideals of twisted S ∕ R S∕R-forms of the algebra of currents g ( R ) g(R) are in natural bijection with ...
Algebraic constructions of densest lattices
(Elsevier B.V., 2015-05-01)
The aim of this paper is to investigate rotated versions of the densest known lattices in dimensions 2, 3, 4, 5, 6, 7, 8, 12 and 24 constructed via ideals and free Z-modules that are not ideals in subfields of cyclotomic ...
On the existence and stability of periodic orbits in non ideal problems: General results
(2007-11-01)
In this work, motivated by non-ideal mechanical systems, we investigate the following O.D.E. ẋ = f (x) + εg (x, t) + ε2g (x, t, ε), where x ∈ Ω ⊂ ℝn, g, g are T periodic functions of t and there is a 0 ∈ Ω such that f (a ...
The Banach ideal of A-compact operators and related approximation properties
(Elsevier, 2013-07-22)
We use the notion of A-compact sets (determined by an operator ideal A), introduced by Carl and Stephani (1984), to show that many known results of certain approximation properties and several ideals of compact operators ...
Compatibility and correlation of multi-attribute decision making: a case of industrial relocation
(2022-01-01)
Industrial relocation (IR) is a business strategy consisting of moving operations locations. The purpose of this paper is to present how to assess, with multi-attribute decision-making (MADM), alternatives for IR. With ...
Application of the center manifold theory to the study of slewing flexible Non-ideal structures with nonlinear curvature: a case study
(The Brazilian Society of Mechanical Sciences, 2002-07)
In this paper is Analyzed the local dynamical behavior of a slewing flexible structure considering nonlinear curvature. The dynamics of the original (nonlinear) governing equations of motion are reduced to the center ...
