Bäcklund transformations associated with the Korteweg-deVries (KdV), modified KdV, and nonlinear Schrödinger equations are derived by a method due to Clairin. Also, a Bäcklund transformation relating the KdV and modified KdV equations is obtained by the same technique.
G. L. Lamb (1974) studied this question.
