New multisoliton solutions of the Kadomtsev-Petviashvili equation
Pelinovskii D. E. , Stepanyants Yu. A.
A new class of exact rational solutions has been found for the Kadomtsev-Petviashvili equation which describes wave processes in media with a positive dispersion. These solutions represent spatially localized, steady-state multisolitons, which may be thought of as bound states of individual solitons.
