Canonical quadratic refinements of cohomological pairings from functorial lifts of the Wu class
arXiv:1208.1540
Abstract
As mentioned in the comments, the proposed construction of the canonical quadratic refinement on a mapping torus contains a gap. In addition, the claim in the appendix that the spin cobordism group vanishes in dimensions 4k+3 is incorrect, although it does vanish for the case of dimension 7, relevant for physics.
This paper has been withdrawn because there is a gap in the construction of the canonical quadratic refinement on a mapping torus
