Existence and uniqueness of solutions for delay stochastic evolution equations of second order in time
(World Scientific Publishing, 2003-06)
We prove some results on the existence and uniqueness of solutions for a class of evolution equations of second order in time, containing some hereditary characteristics. Our theory is developed from a variational point ...

QSI - Alternative Labelling and Noise Sensitivity
(University of Brasilia, 2003-08)
The are different approaches to the temporal study of time evolving systems. In the paper, this study is carried out by means of the comparison of the time series. This paper continues previous Works on QSI and studies the ...

Some limit relations in the A1 tableau of Dunkl-Cherednik operators
(Elsevier, 2003-12-15)
In this paper we study some limit relations involving some q-special functions related with the A1 (root system) tableau of Dunkl-Cherednik operators. Concretely we consider the limits involving the nonsymmetric q-ultraspherical ...

Towards a Practical Argumentative Reasoning with Qualitative Spatial Databases
(Springer, 2003)
Classical database management can be flawed if the Knowledge database is built within a complex Knowledge Domain. We must then deal withinconsistencies and, in general, withanomalies of several types. In this paper we ...

Bases for Projective modules in An(k)
(2003-12)
Let $A_n(k)$ be the Weyl algebra, with $k$ a field of characteristic zero. It is known that every projective finitely generated left module is free or isomorphic to a left ideal. Let $M$ be a left submodule of a free module. ...

Trasplante de células naturales "dopaminotróficas" nuevo concepto terapeútico antiparkinsoniano
(Viguera, 2003)
Aim and method. Parkinson's disease is caused by the degeneration of dopamineric neurons of substantia nigra projecting to striatum. Cellular substitution represents a potentially treatment once beneficial levodopa effects ...

Using the finite domain remnant of the continuous spectrum to examine integrability: Effect of boundary conditions
(2003)
The aim of this work is to propose a method for testing the integrability of a model partial differential (PDE) and/or differential difference equation (DDE), by examining it in a finite but large domain. For monoparametric ...

Minimal resolutions of lattice ideals and integer linear programming
(European Mathematical Society, 2003)
A combinatorial description of the minimal free resolution of a lattice ideal allows us to the connection of Integer Linear Programming and Algebra. The non null reduced homology spaces of some simplicial complexes are ...
