The Splitting of Generalisations of the Fadell-Neuwirth short exact sequence
Daciberg Lima Gonçalves, John Guaschi, Carolina de Miranda e Pereiro
We study some generalisations to mixed braid groups of the Fadell-Neuwirth short exact sequence and the possible splitting of this sequence. In certain cases, we determine conditio…

The BNS invariants of the braid groups and pure braid groups of some surfaces
Carolina de Miranda e Pereiro, Wagner Sgobbi
We compute and explicitly describe the Bieri-Neumann-Strebel invariants for the full and pure braid groups of the sphere , the real projective plane $\mathbb{R}…

The Borsuk-Ulam theorem for n-valued maps between surfaces
Vinicius Casteluber Laass, Carolina de Miranda e Pereiro
In this work we analysed the validity of a type of Borsuk-Ulam theorem for multimaps between surfaces. We developed an algebraic technique involving braid groups to study this prob…
