Berna Sepúlveda, Isabel (Data de defensa: 2012-02-10)
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 ...
Luque Jimenez, Alejandro (Data de defensa: 2010-01-12)
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 (Data de defensa: 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 ...
Fortuny Anguera, Gerard (Data de defensa: 2009-02-20)
En aquesta tesi es construeix un simulador numèric de la paret abdominal inferior, per tal de determinar la gènesis i les causes de les hernies inguinal humanes. Així, un model amb dades reals d'aquesta ...
García Planas, María Isabel (Data de defensa: 1994-12-15)
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 (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 ...
Simon López, Adrià (Data de defensa: 2015-07-06)
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 ...
