Finite symmetry in finite dimensional integrable systems
T. Tjin
By generalizing the Drinfeld-Sokolov reduction a large class of algebras can be constructed. We introduce 'finite' versions of these algebras by Poisson reducing Kirillov Poiss…

W Algebras, W Gravities and their Moduli Spaces
F. A. Bais, T. Tjin, P. van Driel +2
By generalizing the Drinfel'd--Sokolov reduction we construct a large class of W algebras as reductions of Kac--Moody algebras. Furthermore we construct actions, invariant under lo…
