Abstract

We establish some structural results for the Witt and Grothendieck–Witt groups of schemes over (Formula presented.), including homotopy invariance for Witt groups and a formula for the Witt and Grothendieck–Witt groups of punctured affine spaces over a scheme. All these results hold for singular schemes and at the level of spectra.
