A four-term exact sequence of fundamental groups of orbit configuration spaces

S. K. Roushon

We deduce that the fundamental groups of the orbit configuration spaces of an effective and properly discontinuous action of a discrete group on a connected aspherical 2-manifold,…

The affine Artin group of type is virtually poly-free

Li Li, S. K. Roushon

In this note we prove that the affine Artin group of type is virtually poly-free. The proof also gives another solution of the problem for $\widetilde B_…

On aspherical configuration Lie groupoids

S K Roushon

The complement of the hyperplanes , for all in , for an aspherical -manifold, is known to be aspherical. Here we consider the situation, when …

A four-term exact sequence of surface orbifold pure braid groups

S K Roushon

We prove a four-term exact sequence of surface orbifold pure braid groups for all genus , -dimensional orientable orbifolds with cone points. This corrects our earlier r…

Orbifold braid groups

S. K. Roushon

The orbifold braid groups of two dimensional orbifolds were defined in [1] (arXiv:math/9907194) to understand certain Artin groups as subgroups of some suitable orbifold braid grou…

k-almost-quasifibrations

S. K. Roushon

In [8](arXiv:2111.06159) we introduced the notion of a k-almost-quasifibration. In this article we update this definition and call it a k-c-quasifibration. This will help us to rel…
