Bi-Hamiltonian Sturcture of Super KP Hierarchy
Abstract
Description
We obtain the bi-Hamiltonian structure of the super KP hierarchy based on the even super KP operator $Λ= θ^{2} + \sum^{\infty}_{i=-2}U_{i} θ^{-i-1}$, as a supersymmetric extension of the ordinary KP bi-Hamiltonian structure. It is expected to give rise to a universal super $W$-algebra incorporating all known extended superconformal $W_{N}$ algebras by reduction. We also construct the super BKP hierarchy by imposing a set of anti-self-dual constraints on the super KP hierarchy.
