On Euler classes of abelian-by-finite groups

Martin Lorenz

Let $G$ be a finitely generated abelian-by-finite group and $k$ a field of characteristic $p \geq 0$ . The Euler class $[k_{G}]$ of $G$ over $k$ is the class of the trivial $k G$ -module…

Fields of definition for division algebras

Martin Lorenz, Zinovy Reichstein, Louis H. Rowen +1

Let $A$ be a finite-dimensional division algebra containing a base field $k$ in its center $F$ . We say that $A$ is defined over a subfield $F_{0}$ of $F$ if $A = A_{0} \otimes_{F_{0}} F$ …
