Contribution to the study of invariant manifolds and the splitting of separatrices of parabolic points 

Baldomá, Inmaculada (Date of defense: 2001-01-01)

In general, when beginning to explore any scientific field, one focuses on the generic situations; that is, one centers on the behaviours that appear in “most” of the cases encountered in practice. This ...

Boundedness of the Hilbert Transform on Weighted Lorentz Spaces 

Agora, Elona (Date of defense: 2012-07-13)

The main goal of this thesis is to characterize the weak-type (resp. strong-type) boundedness of the Hilbert transform H on weighted Lorentz spaces Λpu(w). The characterization is given in terms of ...

Human Pose Analysis and Gesture Recognition from Depth Maps: Methods and Applications 

Reyes Estany, Miguel (Date of defense: 2017-02-27)

The visual analysis of humans is one of the most active research topics in Computer Vision. Several approaches for body pose recovery have been recently presented, allowing for better generalization of ...

Invariant manifolds and bifurcations for one-dimensional and two-dimensional dissipative maps 

Tatjer i Montaña, Joan Carles (Date of defense: 1990-03-01)

It is known that for the study of continuous dynamical systems the discret case plays an important role because, with it we can study the continuous one by using the Poincaré return map. In the discret ...

On a Family of Degree 4 Blaschke Products 

Canela Sánchez, Jordi (Date of defense: 2015-03-18)

This PhD thesis belongs to the area of discrete dynamical systems in the complex plane, i.e. the iteration of analytic functions in one complex variable. Given a rational map f from the Riemann sphere ...

Dynamical transport mechanisms in celestial mechanics and astrodynamics problems 

Pérez Palau, Daniel (Date of defense: 2015-11-30)

L’objectiu d’aquesta tesi és afegir una petita fulla a l’arbre del coneixement. En particular a la branca del sistemes dinàmics. La teoria de sistemes dinàmics és la branca de les matemàtiques que estudia ...

On Quasiperiodic Perturbations of Ordinary Differential Equations 

Jorba i Monte, Àngel (Date of defense: 1991-10-11)

In this work we study several topics concerning quasi-periodic time-dependent perturbations of ordinary differential equations. This kind of equations appear as models in many applied problems of Celestial ...

The Primitive Function of an Exact Symplectomorphism. Variational principles, Converse KAM Theory and the problems of determination and interpolation 

Haro, Àlex (Date of defense: 1998-10-02)

We have divided this thesis in four parts:<br/><br/>a) PART I: Exact symplectic geometry (introduction of the problems). This part contains the basic tools of symplectic geometry and outlines the four ...

Stochastic modelling of cellular populations: Effects of latency and feedback 

Sánchez Taltavull, Daniel (Date of defense: 2014-12-12)

L'objectiu principal d'aquesta tesi doctoral és l'estudi de l'efecte de les fluctuacions en poblacions acoblades en sistemes biològics, on cèl·lules en estat latent juguen un paper important. Intentant ...

Computation of Normally Hyperbolic Invariant Manifolds 

Canadell Cano, Marta (Date of defense: 2014-07-04)

The subject of the theory of Dynamical Systems is the evolution of systems with respect to time. Hence, it has many applications to other areas of science, such as Physics, Biology, Economics, etc. and ...
