1. Periodic complex map germs and foliations
Abstract In this paper we study topological and analytical conditions on the orbits of a germ of diffeomorphism in the complex plane in order to obtain periodicity. In particular, we give a simple proof of a finiteness criteria for groups of analytic diffeomorphisms, stated in Brochero Martínez 2003. As an application, we derive some consequences about the

2. TÓPICOS EM TEORIA DE MATHER / TOPICS IN MATHER THEORY
Seja (Es)t o espaço de germes na origem de funções suaves entre os espaços euclidianos de dimensões e t. Nesta dissertação, apresentamos a parte da Teoria de Mather que descreve hipóteses suficientes para k-determinação em (Es)t sob duas ações diferentes, induzindo as chamadas R- e K-equivalências. Um germe é k-determinado se é equivalente a q

3. Invariant of map germ from C^2 to C^3 / Invariantes de germes de aplicações de C^2 em C^3
Let f:(C^2,0) to (C^3,0) be a holomorphic map-germ with corank 1 and f_t a stable perturbation of f. The singular points of f_t are either cross-caps, double points or triple points. The number of cross-caps and the number of triple points of f_t and the Milnor number of the double points curve of f_t are invariants of the germs f. In this work we study form

4. "Variedades de Thom-Boardman, ideais Jacobianos e singularidades de aplicações diferenciáveis" / "Thom-Boardman manifolds, jacobian ideals and singularities associate to analitic map germs"
In this work we study the relation between the Thom-Boardman manifolds and the iterated jacobian ideals associate to these manifolds. First, we study the Thom-Boardman singularities associate to analitic map germs with the objective to introduce Thom-Boardman manifolds in the jet space. After, we study the extended jacobians ideals, following Morin s constru
