Invariants of reflection groups, arrangements, and normality of decomposition classes in Lie algebras
J. Matthew Douglass, Gerhard Roehrle
Suppose that W is a finite, unitary, reflection group acting on the complex vector space V and X is a subspace of V. Define N to be the setwise stabilizer of X in W, Z to be the po…
The strong Centre Conjecture: an invariant theory approach
Michael Bate, Benjamin Martin, Gerhard Roehrle
The aim of this paper is to describe an approach to a a strengthened form of J. Tits' Centre Conjecture for spherical buildings. This is accomplished by generalizing a fundamental…
Complete reducibility and separable field extensions
Michael Bate, Benjamin Martin, Gerhard Roehrle
Let G be a connected reductive linear algebraic group. The aim of this note is to settle a question of J-P. Serre concerning the behaviour of his notion of G-complete reducibility…
