Abstract

It is shown that the solutions of the pure initial-value problem for the KP and regularized KP equations are the same, within the order of accuracy attributable to either, on the time scale 0tε3/2, during which nonlinear and dispersive effects may accumulate to make an order-one relative difference to the wave profiles.
