Sy. Lou, GENERALIZED DROMION SOLUTIONS OF THE (2-DIMENSIONAL KDV EQUATION(1)), Journal of physics. A, mathematical and general, 28(24), 1995, pp. 7227-7232
The rich dromion structures for a (2 + 1)-dimensional KdV equation are
revealed. The dromions in a high dimensional integrable model may hav
e a free shape in one or more directions. Multi-dromion solutions can
be driven by perpendicular line, non-perpendicular line and curved lin
e ghost solitons.
