43 p, 528.6 KB Differentiable invariant manifolds of nilpotent parabolic points / Cufí Cabré, Clara (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Fontich, Ernest 1955- (Universitat de Barcelona. Departament de Matemàtiques i Informàtica)
We consider a map F of class Cr with a fixed point of parabolic type whose differential is not diagonalizable, and we study the existence and regularity of the invariant manifolds associated with the fixed point using the parameterization method. [...]

Laboratoire de Mathématiques et Physique Théorique)
It is well-known that the existence of traveling wave solutions for reaction-diffusion partial differential equations can be proved by showing the existence of certain heteroclinic orbits for related autonomous planar differential equations. [...]

Let X be a germ of holomorphic vector field at 0 2 Cn and let E be a linear subspace of Cn which is invariant for the linear part of X at 0. We give a suficient condition that imply the existence of a non-singular invariant manifold tangent to E at 0. [...]

68 p, 5.5 MB Computing invariant manifolds for libration point missions / Mondelo González, José María (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
The goal of this lecture is to review several methodologies for the computation of invariant manifolds, having in mind the needs of preliminary mission design of libration point missions. Because of this, the methods reviewed are developed for and applied to the circular, spatial restricted three-body problem (RTBP), although most of them can be applied with few changes, or almost none, to general dynamical systems. [...]

Departament de Matemàtica Aplicada i Anàlisi) ; Mondelo González, José María (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
The main goal is to give an explanation of transport in the Solar System based in dynamical systems theory. More concretely, we consider as an approximation of the Solar System, a chain of independent Bicircular problems in order to get a first insight of transport in this simplified case. [...]

Aquesta tesi tracta l'estudi de varietats invariants i òrbites periòdiques de sistemes dinàmics discrets i continus. La memòria està dividida en dues parts que es poden llegir de manera independent. [...]
Esta tesis trata sobre el estudio de variedades invariantes y órbitas periódicas de sistemas dinámicos discretos y continuos. La memoria se divide en dos partes que se pueden leer de forma independiente. [...]
This thesis concerns the study of invariant manifolds and periodic orbits of discrete and continuous dynamical systems. The memoir is divided into two parts that can be read independently. The first part (Chapters 1-6) is dedicated to the study of invariant manifolds associated with parabolic points and parabolic invariant tori. [...]
