Essential dimension of quadruples of quaternion algebras
The question of essential dimension of n-tuples of quaternion algebras was studied in depth by Cernele and Reichstein, but the case of n=4 remained open.We study this case over fields of characteristic 2, and bound it by 4 and 5 from below and above, respectively.The talk is based on joint work with Bingöl and Laghribi.
