Symbolic Representation and Classification of N=1 Supersymmetric   Evolutionary Equations
  We extend the symbolic representation to the ring of N=1 supersymmetric differential polynomials, and demonstrate that operations on the ring, such as the super derivative, Frechet derivative and super commutator, can be carried out in the symbolic way. Using the symbolic representation, we classify scalar $\lambda$-homogeneous N=1 supersymmetric evolutionary equations with nonzero linear term when $\lambda>0$ for arbitrary order and give a comprehensive description of all such integrable equations.
