The super Korteweg-de Vries equation, first proposed by Kupershmidt in 1984, is changed into a super extension of the Schwarzian Korteweg-de Vries equation by proper changes of variables. Furthermore based on a simple conservation law, a reciprocal transformation is defined and generates a super Harry Dym equation from the super Schwarzian KdV equation. For a supersymmetric Harry Dym equation first constructed by Brunelli, Das and Popowicz in 2003, a reciprocal transformation is established on its component form and converts the supersymmetric Harry Dym equation to a super equation which is not supersymmetric. |
