Rigid division algebras

Abstract:
It is shown that finite-dimensional division algebras over finitely generated fields do not form rigid rings. Multiplicative groups of such algebras have central automorphisms which do not extend to automorphisms of the algebras themselves.
Keywords:
finite-dimensional division algebra, finitely generated field, rigid algebra, automorphism.
