The original interest in sandwiched singularities comes from a natural question posed by J. Nash in the early sixties to H. Hironaka: “Does a finite succession of Nash transformations or normalized Nash ...
Miranda Galcerán, Eva (Fecha de defensa: 2003-09-22)
En esta tesis se estudia el problema de clasificación de estructuras simplécticas definidas en un entorno de una órbita singular compacta de un sistema completamente integrable sobre una variedad ...
Amorós Carafí, Laia (Fecha de defensa: 2016-12-16)
The Langlands program is a vast and unifying network of conjectures that connect the world of automorphic representations of reductive algebraic groups and the world of Galois representations. These ...

The background of this dissertation is the inverse Galois problem.<br/>Which finite groups can occur as Galois groups of an extension of the rational field? This problem was first considered by D. ...

This thesis is about Galois theory.<br/><br/>The development of a Galois theory for differential equations analogous to the classical Galois theory for polynomial equations was already an aim of S. Lie ...

Sigui R l'anell de polinomis amb coeficients en un cos k de característica zero. El nostre objectiu és, tot seguint la linia de recerca encetada per G. Lyubeznik, utilitzar en profunditat la teoria de ...

A first goal of this thesis is to contribute to the knowledge of cohomological properties of non-standard multigraded modules. In particular we study the Hilbert function of a non-standard multigraded ...
Barja Yáñez, Miguel Ángel (Fecha de defensa: 1998-12-21)
In this tesis we study numerical propieties of surfaces and threefolds, mainly fibred over curves, the so called "slope" of the fibration. We prove partially a conjecture of Fujita on the semiampleness ...

To determine whether a syzygy bundle on PN is stable, or semistable, is a long-standing problem in algebraic geometry. It is closely related to the problem of finding the Hilbert function and the minimal ...
Costa Farràs, Laura (Fecha de defensa: 1998-09-01)
This thesis seeks to contribute to a deeper understanding of the moduli spaces <i>M-sub X, H (r; c1,., Cmin{r;n}</i>) of rank <i>r</I>, <i>H</i>-stable vector bundles E on an <i>n</i>-dimensional variety ...
