1. Memoria e imagen
Image and narration are intrinsically related when the transmission of memory is at stake. This is so, not only because of the iconic dimension of the words, that make any story a projective screen of our imagination, but also due to the narrative character of images, although these very often require the proximity of the word. In both cases the idea of tran

2. Grupos de tranças do espaço projetivo / Braid groups of projective plane
Dada uma superfície M, definiremos os grupos de tranças de M, denotado por B IND. n(M), geometricamente e usando a noção de espaços de confiuração. Mostraremos a equivalência das definições. Na mesma linha de raciocínio, definiremos os grupos de tranças puras de superfícies P IND. n(M). Apresentaremos as propriedades mais importantes dos grupos

3. Cálculo das retas numa superfície cúbica em P3
In this work we study cubic surfaces in P3. More specically, we take care to count the number of lines on these surfaces. In chapter one we proved that the number of lines on a non-singular cubic surface in P3 is 27. In chapter two, as the motivation for chapter three, we focused in the classifcation of singularities of plane curves. For the singular case, d

4. Curvas nodais maximais via curvas de Fermat
We study the rational projective nodal plane curves in the projective plane P2(C) by using the Fermat curve Fn : Xn+Y n+Zn = 0. We deal with the theory of dual curves in the projective plane and a special type of group action of Zn x Zn on the Fermat curve and its dual to construct, for any positive integer n maior ou igual a 3, a rational nodal plane curve

5. Estudo geoestrutural do maciÃo de Granito Vermelho Frevo SertÃnia-PE
The purpose of this report is to recommend a new methodology for prospecting ornamental rocks massifs. This is why it is important to supply the technical staff, for the future operations of mining of knowledgement of the petrographic and physical-mechanical features of the rock to be extracted and the regime of tensions to be submitted to define the best sy

6. Um visualizador para uma extensão de CGAL ao plano projetivo orientado / A viewer to an extention of CGAL to the oriented projective plane
Visualizadores são softwares capazes de gerar, através de recursos gráficos computacionais, figuras geométricas a partir de estruturas de dados e seus estados. Suas imagens facilitam a compreensão e depuração de algoritmos, bem como aumentam a intuição do usuário sobre os objetos geométricos e o espaço que os abriga. O presente trabalho descreve

7. Collinearity-preserving functions between Desarguesian planes
Using concepts from valuation theory, we obtain a characterization of all collinearity-preserving functions from one affine or projective Desarguesian plane into another. The case in which the planes are projective and the range contains a quadrangle has been treated previously in the literature. Our results permit one or both planes to be affine and include
