This thesis explores the explicit computation of twists of curves. We develope an algorithm for computing the twists of a given curve assuming that its automorphism group is known. And in the particular case in which the ...
El trabajo se centra en los juegos cooperativos con utilidad transferible, que son excelentes modelos matemáticos para analizar situaciones de conflicto y cooperación entre diversos agentes. Consta de dos partes.<br/><br/>En ...
The main objects of study in this thesis are matroids. In particular we are interested in three particular classes matroids: regular matroids, arithmetic matroids, and internally perfect matroids. Of these families, regular ...
This thesis presents new applications of Gale duality to the study of polytopes with extremal combinatorial properties. It consists in two parts. The first one is devoted to the construction of neighborly polytopes and ...
Many of the problems in experimental sciences and other disciplines can be expressed in the form of nonlinear equations. The solution of these equations is rarely obtained in closed form. With the development of computers, ...
This thesis explores one of the essential arithmetical and diophantine properties of Shimura curves and their Atkin-Lehner quotients: the existence of rational points on these families of curves over both number fields and ...
En esta memoria se estudian diferentes problemas dinámicos relacionados con la termomecánica racional. En el primer capitulo se hace un breve repaso a los distintos tipos de problemas a estudiar y de las herramientas a ...
