不同伦等价于球楔的分划格拓扑的商

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

Ralf Donau

摘要:

doi:10.1016/j.topol.2010.08.006的读者可能会猜想Δ(PDMATHABMM_n)/G同伦等价于一个球楔,对任意n>=3和任意子群G<S_n。通过证明对任意素数p>=5,Δ(PDMATHABMM_p)/C_p不是球面楔的同伦等价,我们证明了这一点.

英文摘要:

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 by showing that Δ(\barΠ_p)/C_p is not homotopy equivalent to a wedge of spheres for any prime number p>=5.
