The set of division algebras central and finite dimensional over a field F ลฝ . are nicely parameterized by the Brauer group Br F , which is naturally 2 ลฝ โ ท . isomorphic to the Galois cohomology group H G , F . Since the latter F sep is an arithmetic invariant, the theory of F's division algebras and

For a faithful ZG lattice A and a field K on which the group G acts by field automorphisms, let R be the normal subgroup generated by the elements of G which act trivially on K and act as reflections on A. We prove that the rationality G such that GrR ( โ . We then use this reduction result to prov
