我们使用Fox-Neumerth细胞结构的配置空间的一点紧作为起点,了解我们最近的计算对称群的模2上同调。然后,我们使用该计算给出简短的证明经典的结果上同调由于中冈和马德森。
We use the Fox-Neuwirth cell structure for one-point compactifications of configuration spaces as the starting point for understanding our recent calculation of the mod-two cohomology of symmetric groups. We then use that calculation to give short proofs of classical results on this cohomology due to Nakaoka and to Madsen.
