    "abstract": "We show that the auto-Backlund transformations of the sine-Gordon,\nKorteweg-deVries, nonlinear Schrodinger, and Ernst equations are related to\ntheir respective CPT symmetries. This is shown by applying the CPT symmetries\nof these equations to the Riccati equations of the corresponding\npseudopotential functions where the fields are allowed to transform into new\nsolutions while the pseudopotential functions and the Backlund parameter are\nheld fixed.",
