Zachary Himes

AI总结:

本文证明了连通流形无序构型空间同调的次同调稳定性,通过构造新的链层级稳定化映射解决了闭流形情形下缺乏诱导稳定性映射及同调呈周期性的难题。

摘要:

次同调稳定性是一种近期发现的稳定性模式,适用于在通常同调稳定性不成立的范围内已表现出同调稳定性的空间序列的同调。我们证明了连通流形无序构型空间同调的次同调稳定性。主要困难在于流形为闭流形的情形,因为此时不存在诱导稳定性的明显映射,且同调最终呈现周期性而非稳定性。我们通过为构型空间构造新的链层级稳定化映射解决了该问题。

英文摘要:

Secondary homological stability is a recently discovered stability pattern for the homology of a sequence of spaces exhibiting homological stability in a range where homological stability does not hold. We prove secondary homological stability for the homology of the unordered configuration spaces of a connected manifold. The main difficulty is the case that the manifold is closed because there are no obvious maps inducing stability and the homology eventually is periodic instead of stable. We resolve this issue by constructing a new chain-level stabilization map for configuration spaces.
