We obtain a class of examples of non-rational adjoint classical groups of type 2 A n and a group of type 2 D 3 over the function field F of a smooth geometrically integral curve over a p-adic field with p = 2. We also show that for any group of type C n over F , the group of rational equivalence classes of G over
Let F be a Henselian field of q-cohomological dimension 3, where q is a prime. Let Γ F be the totally ordered abelian value group of F and let D be a central division algebra over F of index a power of q such that the characteristic of the residue field, F is coprime to q. We show that when 1 ≤ dim Fq (Γ F /qΓ F ) ≤ 3, the reduced Whitehead group of D is trivial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
