Nonsingularity of the Direct Scattering Transform for the KP II Equation with a REal Exponentially Decaying-at-Infinity Potential



We study the direct spectral transform for the heat equation associated with the Kadomtsev-Petviashvili. We show that, for real nonsingular exponentially decaying-at-infinity potential, the directproblem is nonsingular for arbitrarily large potentials. Earlier, thisstatement was proved only for potentials satisfying the ‘small norm’assumption.
