Algebraic integrability of foliations by extension to Hirzebruch surfaces. Applications to bounded negativity. 

    Pérez-Callejo, Elvira (Date of defense: 2023-12-21)

    We make progress on two open mathematical problems: the problem of algebraic integrability of polynomial foliations on $\mathbb{C}^2$ and the bounded negativity conjecture. For the first one, we identify $\mathbb{C}^2$ ...

    Bounded sets in topological groups 

    Chis, Cristina (Date of defense: 2010-02-09)

    A boundedness structure (bornology) on a topological space is an ideal of subsets containing all singletons, that is, closed under taking subsets and unions of finitely many elements. In this paper we deal with the structure ...

    El cono de curvas asociado a una superficie racional. Poliedricidad. 

    Monserrat Delpalillo, Francisco José (Date of defense: 2003-07-23)

    A una superficie proyectiva X cualquiera se le pueden asociar una serie de conos convexos (cono de curvas, cono semiamplio y cono característico) que proporcionan información sobre la geometría de la superficie. En esta ...
