| Abstract: | By means of variable separation approach, quite a general excitation of the new (2+1)-dimensional long dispersivewave system: λqt+qxx-2q∫ (qr)xdy=0, λrt-rxx+2r∫ (qr)xdy=0, is derived. Some types of the usual localized excitations such as dromions,lumps, rings, and oscillating soliton excitations can be easilyconstructed by selecting the arbitrary functions appropriately. Besides these usual localized structures, some new localizedexcitations like fractal-dromion, fractal-lump, and multi-peakonexcitations of this new system are found by selecting appropriate functions. |
