Supersymmetric KdV equation: Darboux transformation and discrete systems (1311.0152v1)
Published 1 Nov 2013 in nlin.SI, math-ph, and math.MP
Abstract: For the supersymmetric KdV equation, a proper Darboux transformation is presented. This Darboux transformation leads to the B\"{a}cklund transformation found early by Liu and Xie \cite{liu2}. The Darboux transformation and the related B\"{a}cklund transformation are used to construct integrable super differential-difference and difference-difference systems. The continuum limits of these discrete systems and of their Lax pairs are also considered.
