Noncyclic Division Algebras over Fields of Brauer Dimension One
Published 21 Mar 2019 in math.RA | (1903.09063v1)
Abstract: Let $K$ be a complete discretely valued field of rank one, with residue field $\Q_p$. It is well known that period equals index in $\Br(K)$. We prove that when $p=2$ there exist noncyclic $K$-division algebras of every $2$-power degree divisible by four. Otherwise, every $K$-division algebra is cyclic.
