Cohomological invariants for G-Galois algebras and self-dual normal bases
Eva Bayer-Fluckiger, Raman Parimala
We define degree two cohomological invariants for G-Galois algebras over fields of characteristic not 2, and use them to give necessary conditions for the existence of a self--dual…
Embeddings of maximal tori in classical groups and explicit Brauer-Manin obstruction
Eva Bayer-Fluckiger, Ting-Yu Lee, Raman Parimala
Embeddings of maximal tori into classical groups over global fields of characteristic not 2 are the subject matter of several recent papers, with special attention to the Hasse pri…
On the u-Invariant of Function Fields of Curves Over Complete Discretely Valued Fields
R. Parimala, V. Suresh
Let K be a complete discretely valued field with residue field k. If char(K) = 0, char(k) = 2 and the 2-rank of k is d, we prove that there exists an integer N depending on d such…
The Kneser-Tits conjecture for groups with Tits-index E_{8,2}^{66} over an arbitrary field
R. Parimala, J. -P. Tignol, R. M. Weiss
We prove: (1) The group of multipliers of similitudes of a 12-dimensional anisotropic quadratic form over a field K with trivial discriminant and split Clifford invariant is genera…
