Cohomological invariants of classical Weyl groups modulo 2 (1112.6290v3)
Published 29 Dec 2011 in math.AG
Abstract: In a previous paper, we showed that all the cohomological invariants of Weyl groups are completely determined by their restrictions to the abelian subgroups generated by reflections. Using this principle, we describe all the cohomological invariants of the Weyl groups of classical type modulo 2.
