Algebras of distributions suitable for phase‐space quantum mechanics. II. Topologies on the Moyal algebra
(1988-06-04)
The topology of the Moyal *-algebra may be defined in three ways: the
algebra may be regarded as an operator algebra over the space of
smooth declining functions either on the configuration space or on the
phase space ...
REVISTA SERENGUETI 2(1)
(2020)
En los últimos años, el estudiantado del Bachillerato en Estadística de nuestra escuela ha realizado trabajos con múltiples técnicas estadísticas, que se aplican a diversas áreas del conocimiento. Darnos cuenta de la riqueza ...
The role of short-term immigration on disease dynamics: An SIR model with age-structure
El rol de la inmigración en periodos cortos sobre la dinámica de enfermedades: un modelo sir con estructura de edad
(2019-02-18)
We formulate an age-structured nonlinear partial differential equation model that features short-term immigration effects in a population. Individuals can immigrate into the population as any of the three stages in the ...
The local index formula for SU_q(2)
(2005)
We discuss the local index formula of Connes-Moscovici for the isospectral noncommutative geometry that we have recently constructed on quantum SU(2). We work out the cosphere bundle and the dimension spectrum as well as ...
Testing one-body density functionals on a solvable model
(2012-10)
There are several physically motivated density matrix functionals in the literature, built from the knowledge of the natural orbitals and the occupation numbers of the one-body reduced density matrix. With the help of the ...
On the ultraviolet behaviour of quantum fields over noncommutative manifolds
(1999-03)
By exploiting the relation between Fredholm modules and the Segal-Shale-Stinespring version of canonical quantization, and taking as starting point the first-quantized fields described by Connes' axioms for noncommutative ...
The set of fiber-bunched cocycles with nonvanishing Lyapunov exponents over a partially hyperbolic map is open
(2018)
We prove that the set of fiber-bunched SL(2, R)-valued Hölder cocycles with nonvanishing Lyapunov exponents over a volume preserving, accessible and center-bunched partially hyperbolic diffeomorphism is open. Moreover, we ...
El problema de los subespacios invariantes
(1983-11)
El Prof. Carl Pearcy, de la Universidad de Michigan en Ann Arbor, visitó la Escuela de Matemática en noviembre de 1983, y ofreció un minicurso de tres sesiones sobre el problema de los subespacios invariantes. Dicho problema ...
Estrategias asociadas al uso de GeoGebra en un contexto de resolución de problemas
Strategies associated with the use of GeoGebra in a problem-solving context
Estratégias associadas ao uso do GeoGebra em um contexto de resolução de problemas
(2021-01-15)
Este artículo presenta una experiencia en aula de matemática cuyo objetivo fue analizar cómo el uso constante de un Sistema de Geometría Dinámica (SGD), GeoGebra, en un contexto de resolución de problemas, permitió a un ...
Connes' tangent groupoid and strict quantization
(1999-12)
We address one of the open problems in quantization theory recently listed by Rieffel. By developing in detail Connes' tangent groupoid principle and using previous work by Landsman, we show how to construct a strict flabby ...
