Abstract: 
The inverse scattering theory of perturbed KadomtsevPetviashvili II one line solitons is completed by providing rigorous spectral analysis to solve a singular Cauchy integral equation. An existence theorem for global solution for the Cauchy problem of the perturbed KPII 1 line solitons is justified by deriving a functional calculus of the evolution equation based on the inverse scattering theory.
