Binary Darboux-Backlund transformations for the Manin-Radul super KdV hierarchy

Abstract

We construct the supersymmetric extensions of the Darboux-Backlund transformations (DBTs) for the Manin-Radul super Korteweg-de Vries (KdV) hierarchy using the super-pseudo-differential operators. The elementary DBTs are triggered by the gauge operators constructed from the wave functions and adjoint wave functions of the hierarchy. Iterating these elementary DBTs, we obtain not only Wronskian-type but also binary-type superdeterminant representations of the solutions. (C) 1998 American Institute of Physics.
