A note on the third family of N=2 supersymmetric KdV hierarchies
Abstract
We propose a hamiltonian formulation of the
N=2
supersymmetric KP type hierarchy recently studied by Krivonos and Sorin. We obtain a quadratic hamiltonian structure which allows for several reductions of the KP type hierarchy. In particular, the third family of
N=2
KdV hierarchies is recovered. We also give an easy construction of Wronskian solutions of the KP and KdV type equations.
