Cofibre-colimit model for coarse homology at infinity
Cofibre-colimit model for coarse homology at infinity
Let be a coarse homology theory, let be a uniform bornological coarse space, and let be the canonical inclusions associated to a uniform shape expansion, with cofibre . Assume that is complete and that is additive. Cofibre-colimit conjecture. There is an equivalence
This would identify the coarse homology at infinity of with a colimit of locally finite cofibres arising from its uniform shape model.
