INTEGRABILITY OF CLASSICAL AFFINE W-ALGEBRAS
Keyword(s):
AbstractWe prove that all classical affine W-algebras 𝒲(𝔤; f), where g is a simple Lie algebra and f is its non-zero nilpotent element, admit an integrable hierarchy of bi-Hamiltonian PDEs, except possibly for one nilpotent conjugacy class in G2, one in F4, and five in E8.
