Stable Pontryagin-Thom construction for proper maps II
Abstract: In arXiv:1905.07734 we presented a construction that is an analogue of Pontryagin's for proper maps in stable dimensions. This gives a bijection between the cobordism set of framed embedded compact submanifolds in $W\times\mathbb{R}n$ for a given manifold $W$ and a large enough number $n$, and the homotopy classes of proper maps from $W\times\mathbb{R}n$ to $\mathbb{R}{k+n}$. In the present paper we generalise this result in a similar way as Thom's construction generalises Pontryagin's. In other words, we present a bijection between the cobordism set of submanifolds embedded in $W\times\mathbb{R}n$ with normal bundles induced from a given bundle $\xi\oplus\varepsilonn$, and the homotopy classes of proper maps from $W\times\mathbb{R}n$ to a space $U(\xi\oplus\varepsilonn)$ that depends on the given bundle. An important difference between Thom's construction and ours is that we also consider cobordisms of non-compact manifolds after indroducing a suitable notion of cobordism relation for these.
