交换元的位形空间

Configuration spaces of commuting elements

José Cantarero, Ángel R. Jiménez

摘要:

本文引入了拓扑群中交换元的位形空间,并证明了它对酉群、特殊酉群和辛群序列都满足有理同调稳定性。我们还证明了它满足上同调的有理表示稳定性的有限产品的元组中的元素的数量,特别是空间的无序配置的交换元素的上同调的有理稳定性。最后给出了不稳定域上同调的一些计算方法。

英文摘要:

In this article we introduce the space of configurations of commuting elements in a topological group and show that it satisfies rational homological stability for the sequences of unitary, special unitary and symplectic groups. We also prove that it satisfies cohomological rational representation stability with respect to the number of elements in the tuple for finite products of such groups, in particular cohomological rational stability for the space of unordered configurations of commuting elements. Finally we present some computations of cohomology in the unstable range.
