On the Witt groups of projective bundles and split quadrics: geometric reasoning, by Alexander Nenashev

Formulas for the derived Witt groups of projective bundles are obtained. We deduce them from general properties of Witt theory, with the help of twisted Thom isomorphisms, avoiding explicit use of triangulated categories. Witt groups of completely split quadrics are also considered.
