Multisoliton excitations for the Kadomtsev–Petviashvili equation and the coupled Burgers equation

In high dimensions, there are abundant coherent soliton excitations. From the variable separation approach of the celebrated Kadomtsev–Petviashvili(KP) equation and the coupled Burgers equation, several new multisoliton excitations are derived and some novel features or interesting behaviors of these structures are revealed.
