Generalização da sequência curta de Fadell-Neuwirth para os grupos de tranças de superfícies
Dutra, Éderson Ricardo Frühling (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, , 17/02/2014)The objective of this work is to study the braid groups on topological surfaces as well as studying a generalization of the Fadell-Neuwirth short exact sequence. We treated also the existence of a cross-section for the ...
