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 for a given manifold and a large enough number , and the homotopy classes of proper maps from to . 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 with normal bundles induced from a given bundle , and the homotopy classes of proper maps from to a space 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.
