Algunas fórmulas útiles para productos torcidos
(1986)
Investigamos dos modificaciones del producto cuántico o torcido de
funciones sobre el espacio de fases, y proporcionamos una colección de
fórmulas útiles en el cálculo con estos productos. La primera
modificación es la ...
Algebras of distributions suitable for phase‐space quantum mechanics. I
(1988-06-04)
The twisted product of functions on R^2N is extended to a *-algebra of
tempered distributions which contains the rapidly decreasing smooth
functions, the distributions of compact support, and all polynomials,
and moreover ...
The Stratonovich-Weyl correspondence: A general approach to Wigner functions
(1989)
A formalism is proposed for developing phase-space representations of
elementary quantum systems under general invariance groups. Several
examples are discussed, including the usual Weyl calculus, the Moyal
formulation ...
Una fundamentación instrumental de la Aritmética
(1990)
Desde el punto de vista de la génesis histórica y psicológica del conocimiento humano, poca duda cabe que los números naturales van siendo elaborados como referente social en el proceso de conteo. En este artículo se ...
Resolución de la ecuación de tercer grado por aproximaciones sucesivas
(1990)
Se presenta un método numérico iterativo para encontrar las raíces reales de la ecuación de tercer grado reducida x^3 + Bx + C = 0. El método no requiere partir con un cálculo aproximado de la raíz. Las fórmulas de recurrencia ...
A nonlinear relapse model with disaggregated contact rates: Analysis of a forward-backward bifurcation
(2023-09)
Throughout the progress of epidemic scenarios, individuals in different health classes are expected to have different average daily contact behavior. This contact heterogeneity has been studied in recent adaptive models ...
Variations of Hodge Structures of Rank Three k-Higgs Bundles and Moduli Spaces of Holomorphic Triples
(2020)
There is an isomorphism between the moduli spaces of σ-stable holomorphic triples
and some of the critical submanifolds of the moduli space of k-Higgs bundles of
rank three, whose elements (E, ϕk
) correspond to variations ...

Este artículo apareció originalmente en la revista cultural
semestral Laberintos, publicado por el Instituto de Enseñanza
Superior ÉLAIOS, de Zaragoza, en un número dedicado al Año Mundial
de las Matemáticas (2000). ...
New mixed finite element methods for natural convection with phase-change in porous media
(2019)
This article is concerned with the mathematical and numerical analysis of a steady phase change problem for non-isothermal incompressible viscous flow. The system is formulated in terms of pseudostress, strain rate and ...
Improved Automatic Centerline Tracing for Dendritic and Axonal Structures
(2015-04)
Centerline tracing in dendritic structures acquired from confocal images of neurons is an essential tool for the construction of geometrical representations of a neuronal network from its coarse scale up to its fine scale ...
