Variedades singulares
Abstract in Portuguese
Neste trabalho estudamos índices de campos de vetores em variedades regulares e em variedades com singularidades isoladas. O principal resultado e o Teorema de Poincaré-Hopf que relaciona a característica de Euler de uma variedade com o índice de Poincaré-Hopf do campo. Para intersecções completas com singularidades isoladas, vemos também algumas variações deste teorema que relacionam a característica de Euler com o índice de Schwartz, o índice GSV e o número de Milnor da fibra genérica

Abstract in English
In this work we study some indices of vector fields on regular manifolds, and on manifolds with isolated singularity. The main result is the Poincare-Hopf Theorem, which connects the Euler characteristic with the Poincare-Hopf index of the field. For complete intersections with isolated singularities, we also study some variations of this theorem, which connects the Euler characteristic with the Schwartz index, the GVS index and the Milnor number of the generic fiber
