Drinfeld-Sokolov hierarchies and diagram automorphisms of affine Kac-Moody algebras
Si-Qi Liu, Chao-Zhong Wu, Youjin Zhang +1
For a diagram automorphism of an affine Kac-Moody algebra such that the folded diagram is still an affine Dynkin diagram, we show that the associated Drinfeld-Sokolov hierarchy als…

Central Invariants of the Constrained KP Hierarchies
Si-Qi Liu, Youjin Zhang, Xu Zhou
We compute the central invariants of the bihamiltonian structures of the constrained KP hierarchies, and show that these integrable hierarchies are topological deformations of thei…

An extension of the Kadomtsev-Petviashvili hierarchy and its Hamiltonian structures
Chao-Zhong Wu, Xu Zhou
In this note we consider a two-component extension of the Kadomtsev-Petviashvili (KP) hierarchy represented with two types of pseudo-differential operators, and construct its Hamil…
