群上同调中的诣零

Nilpotence in Group Cohomology

Nicholas J. Kuhn

摘要:

研究紧李群G的分类空间的模p上同调H*(BG)中的零值的界.这部分是我们以前在这个问题上的工作报告,更新以反映彼得西蒙兹最近验证戴夫本森的正则性猜想的结果。对有限p-群给出了新的结果,得到了由p-群P的子群结构决定的H ~*(BP)的零值的好的界.

英文摘要:

We study bounds on nilpotence in H*(BG), the mod p cohomology of the classifying space of a compact Lie group G. Part of this is a report of our previous work on this problem, updated to reflect the consequences of Peter Symonds recent verification of Dave Benson's Regularity Conjecture. New results are given for finite p--groups, leading to good bounds on nilpotence in H*(BP) determined by the subgroup structure of the p--group P.
