Title in Portuguese
Fibrações de Milnor de singularidades analíticas reais
Keywords in Portuguese
Não disponível
Abstract in Portuguese
Neste trabalho estudamos a fibração de Milnor associada a singularidades isoladas reais definidas por germes de aplicações f : Rn, 0 → R2, 0 . O principal resultado relaciona a existência da fibração de Milnor com a (c)-regularidade da família de hipersuperfícies com singularidade isolada obtida projetando f sobre a família L-θ de todas as retas pela origem no plano R2. Estudamos também famílias de germes de funções analíticas com singularidades isoladas. O objetivo é encontrar condições suficientes para a trivialidade topológica das famílias e a equivalência das fibrações de Milnor associadas a elas.

Abstract in English
In this work we study the Milnor's fibrations associated to real isolated singularities defined by map-germs f : Rn, 0 → R2, 0. The main result relates the existence of the Milnor's fibration with the (c)-regularity of the family of hypersurfaces with isolated singularity obtained by projecting f into the family L-θ of all lines through the origin in the plane R2sup. We also study families of germs of analytic functions with isolated singularities. The aim is to get sufficient condition for the topological triviality of the families and the equivalente of the Milnor fibrations associated to them.
