Abstract
We construct the formal solution of the Cauchy problem for
the dispersionless Kadomtsev-Petviashvili equation as application
of the Inverse Scattering Transform for the vector field corresponding to
a Newtonian particle in a time-dependent potential. This is in full analogy
with the Cauchy problem for the Kadomtsev-Petviashvili equation, associated
with the Inverse Scattering Transform of the time dependent Schrödinger
operator for a quantum particle in a time-dependent potential.
