Deformation and Recursion for the N=2 $\alpha=1$ Supersymmetric   KdV-hierarchy
  A detailed description is given for the construction of the deformation of the N=2 supersymmetric $\alpha=1$ KdV-equation, leading to the recursion operator for symmetries and the zero-th Hamiltonian structure; the solution to a longstanding problem.
