A nice acyclic matching on the nerve of the partition lattice

Ralf Donau

The author has already proven that the space $Δ (Π_{n}) / G$ is homotopy equivalent to a wedge of spheres of dimension $n - 3$ for all natural numbers $n \geq 3$ and all subgroups $G\subse…

Quotients of the topology of the partition lattice which are not homotopy equivalent to wedges of spheres

Ralf Donau

The reader of doi:10.1016/j.topol.2010.08.006 might conjecture that Δ(\barΠ_n)/G is homotopy equivalent to a wedge of spheres for any n>=3 and any subgroup G<S_n. We disprove this…
