Webdefined by Wall in [4]. In sections 6, 7 we set up an exact sequence, which through a range of dimensions generalizes the Gysin sequence for a sphere bundle. Using this sequence we define in section 8 an obstruction yfc(y)([Jf"]), which for η ^ 2k— 1 is shown to vanish iff the virtual bundle ψ over the manifold Mn is of geometric dimension g k.

WebAug 16, 2024 · In K-homology you can attach cylindrical ends X 1 × [ 0, ∞) and X 2 × [ 0, ∞) to W and argue that the Gysin maps factor through the Mayer-Vietoris boundary maps on the new object W ′. You then lift the K-homology class on W to a class in a certain K-homology-like group for W'; this requires care since W' is non-compact.
