homology and homotopy groups. The terminology for semi-simplicial complexes will follow John Moore [7]. In particular the face and degeneracy maps of K will be denoted by d: Kn Kn-1 and si:K. -> Kn+1 respectively. 1. The definition

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…

### Steenrod squares in signed simplicial sets

- Mathematics

The cup-i products in semi-simplicial sets are developed following the work in [1]. The category of signed simplicial sets is presented, and using the cup-i product formulas, we find an operation in…

### On the Geometry of 2-Categories and their Classifying Spaces
