Resumen: el documento presenta la primera parte del abordaje a la econometría para Agro Economistas, estudia los temas de la regresión tanto simple como múltiple y la modelación en general, se trata de una progresión en términos de... more
L'état et la gestion des jachères ont été étudiés dans une communauté de l'altiplano bolivien, par une équipe pluridisciplinaire sciences agronomiques et sociales. La généralisation de ces résultats à la dynamique des jachères dans les... more
Presentation of the topic and analysis of the issue: Tiquipaya is a Municipality situated in the peri-urban zone of Cochabamba city, Bolivia. Nowadays, drinking water is distributed by community-based Water Committees and just a small... more

El proyecto MACOTI (Mancomunidad Colcapirhua-Tiquipaya) es un proyecto que persigue la construcción de un sistema centralizado de alcantarillado y agua potable en las zonas urbanas de Tiquipaya y Colcapirhua. La falta de transparencia que... more
An M C group is a group in which all chains of centralizers have finite length. In this article, we show that every nilpotent subgroup of an M C group is contained in a definable subgroup which is nilpotent of the same nilpotence class.... more

We prove a Jordan decomposition theorem for minimal connected simple groups of finite Morley rank with non-trivial Weyl group. From this, we deduce a precise structural description of Borel subgroups of this family of simple groups. Along... more

We prove that in a connected group of finite Morley rank the centralizers of decent tori are connected. We then apply this result to the analysis of minimal connected simple groups of finite Morley rank. Our applications include general... more
It is proved that every torsion-free nilpotent group of finite Morley rank is isomorphic to a matrix group over a field of characteristic zero.
The Arithmetic is interpreted in all the groups of Richard Thompson and Graham Higman, as well as in other groups of piecewise affine permutations of an interval which generalize the groups of Thompson and Higman. In particular, the... more

We investigate the diagonal generating function of the Jacobi-Stirling numbers of the second kind JS(n + k, n; z) by generalizing the analogous results for the Stirling and Legendre-Stirling numbers. More precisely, letting JS(n + k, n;... more

In this paper we provide exact expressions for propagators of noncommutative Bosonic or Fermionic field theories after adding terms of the Grosse-Wulkenhaar type to the usual free action in order to ensure Langmann-Szabo covariance. We... more
In this paper we provide a new proof that the Grosse-Wulkenhaar non-commutative scalar Phi^4_4 theory is renormalizable to all orders in perturbation theory, and extend it to more general models with covariant derivatives. Our proof... more
