Let $SPT_*$ be the simplicial group of simplicial pure twin groups, let $c_{111}$ be the 2-simplex with trivial faces, and let $K_*$ be the smallest simplicial subgroup of $SPT_*$…

Classifying-map conjecture. Under the relevant zigzag of equivalences, the map $N\alpha_*$ is a classifying map for $p:E\to B$: its homotopy class coincides with…
