Abstract: | Starting from an improved projective method and a linear variable
separation approach, new families of variable separation solutions
(including solitary wave solutions, periodic wave solutions and
rational function solutions) with arbitrary functions for the
(2+1)-dimensional generalized Broer-Kaup (GBK) system are derived.
Usually, in terms of solitary wave solutions and/or rational
function solutions, one can find abundant important localized
excitations. However, based on the derived periodic wave solution
in this paper, we reveal some complex wave excitations in the
(2+1)-dimensional GBK system, which describe solitons moving on a
periodic wave background. Some interesting evolutional properties for these solitary waves propagating on
the periodic wave background are also briefly discussed. |
