Recursion Operator and Bäcklund Transformation for Super mKdV Hierarchy

Abstract

In this paper we consider the $\mathcal{N}=1$ supersymmetric mKdV hierarchy composed of positive odd flows embedded within an affine $\hat{s}l(2,1)$ algebra. Its Bäcklund transformations are constructed in terms of a gauge transformation preserving the zero curvature representation. The recursion operator relating consecutive flows is derived and shown to relate their Bäcklund transformations.
