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 ...
