Query: A note on the third family of N=2 supersymmetric KdV hierarchies   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.
