Multiples of Trace Forms and Algebras with Involution
Multiples of Trace Forms and Algebras with Involution
Let k be a field of characteristic ≠ 2, and let G be a finite group. The aim of this article is to give a cohomological criterion for the isomorphism of multiples of trace forms of G-Galois algebras over k. The proof uses results concerning multiples of hermitian forms over …
