Levels and sublevels of composition algebras over $$\mathfrak{p}$$ -adic function fields

Autor: Jan Van Geel, James O'Shea

Publikováno v: Archiv der Mathematik. 91:31-43

In [7], the level and sublevel of composition algebras are studied, wherein these quantities are determined for those algebras defined over local fields. In this paper, the level and sublevel of composition algebras, of dimension 4 and 8 over rationa

Pythagoras numbers of function fields of hyperelliptic curves with good reduction

Autor: Sergey V. Tikhonov, Jan Van Geel, V. I. Yanchevskii

Publikováno v: manuscripta mathematica. 119:305-322

It is shown that the Pythagoras number of a real function field of a hyperelliptic curve C, with good reduction, defined over the real formal power series field is equal to 2. A main tool in the proof is the explicit description of the Brauer group o

The Hasse principle for similarity of hermitian forms

Autor: Jan Van Geel, David W. Lewis, Thomas Unger

Publikováno v: Journal of Algebra. 285(1):196-212

The Hasse principle for similarity is established for restricted classes of skew-hermitian forms over quaternion division algebras with canonical involution and for hermitian forms over division algebras with involution of the second kind. A countere
