19 p, 300.3 KB An extension of the 16th Hilbert problem for continuous piecewise linear-quadratic centers separated by a non-regular line / Esteban, Marina (Universidad de Córdoba. Departamento de Informática y Análisis Numérico) ; Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Valls, Clàudia 1973- (Universidade de Lisboa. Instituto Superior Técnico. Departamento Matemática)
In the last few decades, there has been much interest in studying piecewise differential systems. This is mainly due to the fact that these differential systems allow us to modelize many natural phenomena. [...]

22 p, 1.0 MB Minimal set of periods for continuous self-maps of the eight space / Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Sá, Ana (Universidade Nova de Lisboa. Departamento de Matemática (Portugal))
Let Gk be a bouquet of circles, i. e. , the quotient space of the interval [0,k] obtained by identifying all points of integer coordinates to a single point, called the branching point of Gk. Thus, G1 is the circle, G2 is the eight space, and G3 is the trefoil. [...]

42 p, 5.2 MB Invariant tori in the lunar problem / Meyer, Kenneth R. (University of Cincinnati. Department of Mathematical Sciences) ; Palacian, Jesus F. (Universidad Pública de Navarra. Departamento de Ingeniería Matemática e Informática) ; Yanguas, Patricia (Universidad Pública de Navarra. Departamento de Ingeniería Matemática e Informática)
Theorems on the existence of invariant KAM tori are established for perturbations of Hamiltonian systems which are circle bundle ows. By averaging the perturbation over the bundle ow one obtains a Hamiltonian system on the orbit (quotient) space by a classical theorem of Reeb. [...]
