Witt Decompositions for Hermitean אo-Forms

  • Herbert Gross
Part of the Progress in Mathematics book series (PM, volume 1)


Forms are ε-hermitean; if α ⟼ α* is the antiautomorph ism of the underlying division ring we let T := {α + εα*|α ∈ k} be the additive subgroup of “traces” in k. Traces are symmetric elements of k but the converse does not hold when the characteristic is two.
