Horizontal configurations of points in link complements

Daan Krammer

For any tangle $T$ (up to isotopy) and integer $k \geq 1$ we construct a group $F (T)$ (up to isomorphism). It is the fundamental group of the configuration space of $k$ points in a…

A class of Garside groupoid structures on the pure braid group

Daan Krammer

We construct a class of Garside groupoid structures on the pure braid groups, one for each function (called labelling) from the punctures to the integers greater than 1. The object…

Braid groups are linear

Daan Krammer

In a previous work [11], the author considered a representation of the braid group ρ: B_n\to GL_m(\Bbb Z[q^{\pm 1},t^{\pm 1}]) (m=n(n-1)/2), and proved it to be faithful for n=4. B…
