Title: Orbifold braid groups
Abstract:
The orbifold braid groups of two dimensional orbifolds were defined in [1]
to understand certain Artin groups as subgroups of some suitable orbifold braid groups.
We studied orbifold braid groups in some more detail in [17]
and [18],
to prove the Farrell-Jones Isomorphism conjecture for orbifold braid groups and as a
consequence for some Artin groups. In this article we apply the results from [17] and [18],
to study two aspects of the orbifold braid groups. First we show that the homomorphisms
induced on the orbifold braid groups by the inclusion maps of a generic class of sub-orbifolds of an orbifold are injective.
Then, we prove that the centers of most of the orbifold braid groups are trivial.
