Qualitative analysis of the anisotropic Kepler problem

Casasayas i Mas, Josefa (Date of defense: 1984-01-01)

The anisotropic Kepler problem was introduced by Gutzwiller as a classical mechanical system which approximates the following quantum mechanical system: the study of bound states of an electron near a donor impurity of a ...

Random zero sets of analytic functions and traces of functions in Fock spaces

Buckley, Jeremiah (Date of defense: 2013-06-06)

Interpolating and sampling sequences in spaces of functions are classical subjects in complex and harmonic analysis. A sequence of points is said to be interpolating if, given any collection of values, we can find a function ...

Real analysis in non-euclidean spaces: trees and spaces of homogeneous type

Garcia Domingo, Josep Lluís (Date of defense: 2003-01-01)

DE LA TESIS:<br/><br/>El contenido de esta tesis se enmarca dentro del Análisis Real. En particular, trata del estudio de ciertos problemas de la teoría de pesos, (una referencia clásica sobre esta teoría es el libro de ...

Sequential image analysis for computer-aided wireless endoscopy

Drozdzal, Michal (Date of defense: 2014-05-16)

Wireless Capsule Endoscopy (WCE) is a technique for inner-visualization of the entire small intestine and, thus, offers an interesting perspective on intestinal motility. The two major drawbacks of this technique are: 1) ...

Spaces of bandlimited functions on compact manifolds

Pridhnani, Bharti (Date of defense: 2011-09-09)

This monograph is structured in four chapters. In Chapter 1, we present the context of our problem and the main results proved in this work. We describe the asymptotic behaviour of the reproducing kernel and the ...

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 trobar el significat ...

The Parametrisation method for invariant manifolds of tori in Skew-product lattices and an entire transcendental family with a persistent Siegel disk

Berenguel Montoro, Rubén (Date of defense: 2016-02-02)

In this thesis we consider two different problems in the theory of dynamical systems. Dynamical systems cover a wide array of subjects, from finite dimensional to infinite dimensional, from analytic to statistical viewpoints ...

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 subjects that we have ...

The Role and Usage of Libration Point Orbits in the Earth - Moon System

Alessi, Elisa Maria (Date of defense: 2010-10-04)

In this dissertation, we show the effectiveness of the exploitation of the Circular Restricted Three - Body Problem (CR3BP) in the Earth - Moon framework. We study the motion of a massless particle under the gravitational ...

Transference theory between quasi-Banach function spaces with applications to the restriction of Fourier multipliers.

Rodríguez López, Salvador (Date of defense: 2008-04-07)

In the early 1970 fs, R. Coifman and G. Weiss, generalizing the techniques introduced by A. Calderon, developed a method for transferring abstract convolution type operators, defined on general topological groups, and their ...
