The goal of the thesis is the effective computation of the geometric monodromy, equivalently the monodromy in the fundamental group, for families of compact connected Riemann surfaces (complex algebraic ...

És un fet ben conegut que les solucions quasi-periòdiques juguen un paper rellevant a l'hora d'entendre la dinàmica de problemes amb formulació hamiltoniana, els quals apareixen en una gran quantitat ...
Coulon, Anne-Charline (Date of defense: 2014-07-07)
This thesis focuses on the long time behaviour of solutions to Fisher-KPP reaction-diffusion equations involving fractional diffusion. This type of equation arises, for example, in spatial propagation ...

Las ecuaciones de sistemas lineales de la forma: X'(S)= AX(S) + BU(S) O X (K+1) = AX (K) + BU (K) se identifican de manera natural con las parejas de matrices (A, B) modulo uno, relación de equivalencia ...
Rosa Ibarra, Abraham de la (Date of defense: 2014-06-16)
The goal of this thesis is to show global instability or Arnold's diffusion in the elliptic restricted three body problem (ERTBP) by proving the existence of pseudo-trajectories diffusing along the phase ...
Ibáñez Marcelo, Esther (Date of defense: 2014-12-19)
In this thesis we develop a multi-scale model of the evolutionary dynamics of a population of cells, which accounts for the mapping between genotype and phenotype as determined by a model of the gene ...
Serra Montolí, Joaquim (Date of defense: 2014-06-17)
The thesis is divided into two parts. The first part is mainly concerned with regularity issues for integro-differential (or nonlocal) elliptic and parabolic equations. In the same way that densities ...
Granados Corsellas, Albert (Date of defense: 2012-09-17)
In the first part, we formally study the phenomenon of the so-called big bang bifurcations, both for one and two-dimensional piecewise-smooth maps with a single switching boundary. These are a special ...

En l'article [CKSTT] els autors proven una inestabilitat global per a l'equació de Schrödinger cúbica desenfocant en el tor 2-dimensional. Per aconseguir-ho, detecten un sistema finit d'equacions ...
