Stable Pontryagin-Thom construction for proper maps II
András Csépai
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…

Cobordisms of singular maps
András Csépai
The notion of cobordism of singular maps was introduced around 1980 by A. Szűcs and U. Koschorke independently. As an application, Szűcs used it to compute cobordism groups of imme…

Stable Pontryagin-Thom construction for proper maps
András Csépai
We will present proofs for two conjectures stated in arXiv:1808.08073. The first one is that for an arbitrary manifold , the homotopy classes of proper maps $W\times\mathbb{R}^n…
