Resumen de Frobenius manifolds and central invariants for the Drinfeld�Sokolov bihamiltonian structures

Boris Dubrovin, Si-Qui Liu, Youjin Zhang

• The Drinfeld�Sokolov construction associates a hierarchy of bihamiltonian integrable systems with every untwisted affine Lie algebra. We compute the complete sets of invariants of the related bihamiltonian structures with respect to the group of Miura-type transformations.
