Estructura de álgebra de Poisson de la cohomología de ciertas álgebras de Lie nilpotentes
(2022-07-29)
Si g es un álgebra de Lie, la cohomología H**(g) tiene una estructura de súper-álgebra de
Poisson con producto asociativo súper-conmutativo V y un súper-corchete de Lie {-,-} que se
compatibiliza con el producto \vee en ...
A non-homogeneous poisson model with spatial anisotropy applied to ozone data from Mexico City
(Springer, 2015-06-01)
In this work we consider a non-homogenous Poisson model to study the behaviour of the number of times that a pollutant's concentration surpasses a given threshold of interest. Spatial dependence is imposed on the ...
On the point process of near-record values
(Springer, 2015)
Let be a sequence of independent and identically distributed random variables, with common absolutely continuous distribution . An observation is a near-record if , where and is a parameter. We analyze the point process ...
Somas aleatórias Poisson misturadas e modelos normais misturados associados
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE ESTATÍSTICAPrograma de Pós-Graduação em EstatísticaUFMG, 2020-02-18)
The sum of a random number of random variables, besides being interesting from a probabilistic point of view, appears in applications involving processes that evolve over time. An important and widely studied example is ...
The downward continuation of the disturbing potential based on poisson's integral
(Universidad Nacional (Costa Rica), 2004)
En este artículo se prueban y valoran dos métodos diferentes para la realización de la continuación descendente de potencial perturbante. La importancia del potencial perturbante en geodesia reside en que éste es fundamental ...
Integrability vs supersymmetry: Poisson structures of the pohlmeyer reduction
(Springer, 2011-11-01)
We construct recursively an infinite number of Poisson structures for the supersymmetric integrable hierarchy governing the Pohlmeyer reduction of superstring sigma models on the target spaces AdS(n) x S(n), n = 2, 3, 5. ...

Scaling limit of subcritical contact process
(Elsevier Science, 2017-08)
In this paper we study the subcritical contact process on Zd for large times, starting with all sites infected. The configuration is described in terms of the macroscopic locations of infected regions in space and the ...
Algoritmos para a redução de ruído Poisson e estimativa de parâmetros utilizando distâncias estocásticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2018-06-14)
Noise is present in all applications of digital imaging. Due to its stochastic nature, it is impossible to determine exact procedures to completely remove noise from the image. Thus, the target signal may be affected during ...
