Abstract
One-dimensional solitary wave solutions of the Kadomtsev-Petviashvili equation are unstable to long-wavelength transverse disturbances. Here , the nonlinear development of the instability is investigated. The re sults depend on the size of the system as well as on the allowed pertu rbation wavelengths. The analytical predictions are compared with nume rical simulations. (C) 1998 Elsevier Science B.V.
