| Jun 16, 2017 at 8:10 | comment | added | Mark Grant | Where are you reading about this construction? It seems a bit garbled. Normally you would compose the Thom isomorphism $K^*(X)\cong \tilde{K}^*(Th(N))$ for the normal bundle with the map $\tilde{K}^*(Th(N))\to K^*(Y)$ induced by collapsing the complement of the tubular neighbourhood (I suppose this could be thought of as extending a complex bundle from $Th(N)$ to $Y_+$). This requires that the normal bundle is oriented with respect to $K$-theory, i.e has a spin^c structure. | |
