Abstract:

The main results of this article are certain connections between braid groups and the homotopy groups of the $2$-sphere. The connections are given in terms of Brunnian braids over the disk and over the $2$-sphere. The techniques arise from the natural structure of simplicial and $\Delta$-structures on fundamental groups of configuration spaces.
