Orthogonal representations of affine group schemes and twists of symmetric bundles

Philippe Cassou-Noguès, Ted Chinburg, Baptiste Morin +1

Following Serre's initial work, a number of authors have considered twists of quadratic forms on a scheme Y by torsors of a finite group G, together with formulas for the Hasse-Wit…

Twists of symmetric bundles

Ph. Cassou-Nogues, B. Erez, M. J. Taylor

We establish comparison results between the Hasse-Witt invariants w_t(E) of a symmetric bundle E over a scheme and the invariants of one of its twists E_α. For general twists we de…
