On the trace forms of Galois algebras

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

We study the trace form $q_{L}$ of $G$ -Galois algebras $L / K$ when $G$ is a finite group and $K$ is a field of characteristic different from $2$ . We introduce in this paper the catego…

Derived category invariants and L-series

Philippe Cassou-Noguès, Ted Chinburg, Boas Erez +1

We relate invariants in derived categories associated to tame actions of finite groups on projective varieties over a finite field to zeros of L-functions

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…
