The classification and the conjugacy classes of the finite subgroups of the sphere braid groups

Daciberg Lima Gonçalves, John Guaschi

Let n\geq 3. We classify the finite groups which are realised as subgroups of the sphere braid group B_n(S^2). Such groups must be of cohomological period 2 or 4. Depending on the…

Classification of the virtually cyclic subgroups of the pure braid groups of the projective plane

Daciberg Lima Gonçalves, John Guaschi

We classify the (finite and infinite) virtually cyclic subgroups of the pure braid groups $P_{n} (R P^{2})$ of the projective plane. The maximal finite subgroups of $P_{n} (R P^{2})$ are i…

The braid groups of the projective plane and the Fadell-Neuwirth short exact sequence

Daciberg Lima Gonçalves, John Guaschi

We study the pure braid groups $P_{n} (R P^{2})$ of the real projective plane $R P^{2}$ , and in particular the possible splitting of the Fadell-Neuwirth short exact sequence $1 \to P_m(RP^2…
