Division algebras of degree 4 and 8 with involution

Onglets principaux

Amitsur, Shimshon A. [Hebrew University of Jerusalem] Rowen, Louis H. [Bar-Ilan University] Tignol, Jean-Pierre [UCL]

We develop necessary and sufficient conditions for central simple algebras to have involutions of the first kind, and to be tensor products of quaternion subalgebras. The theory is then applied to give an example of a division algebra of degree 8 with involution (of the first kind), without quaternion subalgebras, answering an old question of Albert; another example is a division algebra of degree 4 with involution (*) has no (*)-invariant quaternion subalgebras.
