    Matroids : h-vectors, zonotopes, and Lawrence polytopes 

    Dall, Aaron Matthew (Date of defense: 2015-02-25)

    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 ...

    Neighborly and almost neighborly configurations, and their duals 

    Padrol Sureda, Arnau (Date of defense: 2013-03-12)

    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 ...

    On iterative methods to solve nonlinear equations 

    Grau Gotés, Ma. Àngela (Maria Àngela) (Date of defense: 2015-01-28)

    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, ...

    Rational points on Shimura curves and Galois representations 

    Vera Piquero, Carlos de (Date of defense: 2014-11-07)

    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 ...
