针对n≥4的闭光滑或拓扑流形,通过构造同伦高度笛卡尔正方形建立自等价空间与法配边理论环空间的关联,推广了Hambleton–Kreck的相关工作。
AI 中文摘要
设M为n维闭光滑或拓扑流形,其中n≥4。我们构造一个同伦高度笛卡尔正方形,将M在其稳定法微丛的Postnikov ℓ-截面(在合适范围内)的同伦自等价空间(M(ℓ)),与表示相关(法)配边理论的(∞+n)重环空间关联起来。这意味着存在由(M(ℓ))的同伦群和某些Lashof配边群构成的相互关联正合序列的编织,为Hambleton–Kreck关于闭定向4维流形的早期工作提供了概念性解释与广泛推广。
英文摘要
Let $M$ be a closed, smooth or topological $n$-manifold, with $n \geq 4$. We construct a homotopy highly cartesian square relating the space ${\mathcal E}(M (\ell))$ of homotopy self-equivalences of $M$ (in a suitable range) over the Postnikov $\ell$-sections of its stable normal microbundle, and an $(\infty + n)$-fold loop space representing an associated (normal) bordism theory. This implies the existence of braids of interlocking exact sequences involving the homotopy groups of ${\mathcal E}(M(\ell))$ and certain Lashof bordism groups, leading to a conceptual explanation and broad generalization of earlier work of Hambleton--Kreck for closed, oriented $4$-manifolds.
