Repeating games and dynamical systems in oil market
Juegos repetitivos y sistemas dinámicos en el mercado del petroleo
We use the modern theory of repetitive games in a model that help understand a market with a cartel like OPEP. We also study a dynamical system Lotka-Volterra type, and we analyze the dynamic behavior of the model.
Circular chains of chinese dice
Cadenas circulares de dados chinos
In this paper we study Chinese dice, mathematical objects similar to ordinary dice but allowing repetition among their face values.We say that a die A is preferred over a die B (written A B) if A wins more frequently ...
Optimal design of networks and routing of computers: practical case
Diseño óptimo de redes y enrutamiento de computadoras: Caso Práctico
This work introduced to the problem of routering and optimum design of networks of computers that must satisfy certain practical conditions of interconnectivity. This paper show an approach style Steiner problems, and ...
Automatic selection of the p-value in survival curves comparisonautomatic selection of the p-value in survival curves comparison
Seleccion automática del p-valor en la comparación de curvas de supervivencia
In this paper, an algorithm for the automatic selection of an ad-equate test for the survival curves comparison is developed. Theintroduced procedure is an adaptation of the double minimum algo-rithm for the bandwidth ...
Algebraic jet spaces and Zilber’s dichotomy in DCFA
Espacios de jets algebraicos y la dicotomía de Zilber en DCFA
This is the first of two papers devoted to the proof of Zilber’s dichotomy for the case of difference-differential fields of characteristic zero. In this paper we use the techniques exposed in  to prove a weaker version ...
On the stability of certain perturbed systems of differential equations and the relationship with the magnitude of the perturbation
Sobre la estabilidad de ciertos sistemas perturbados de ecuaciones diferenciales y sus relaciones con la magnitud de la perturbación
In this work we consider a class of polytopes of third order squarematrices, studied early. We obtain a condition to guarantee Hurwitzstability of each of elements of the polytope. This condition is moresimples than one ...
