Abstract
The KdV equation is used as an example to illustrate the
relation between the restricted flows and the soliton equation
with self-consistent sources. Inspired by the results on the
Bäcklund transformation for the restricted flows (by V.B.
Kuznetsov et al.), we constructed two types of Darboux
transformations for the KdV equation with self-consistent sources
(KdVES). These Darboux transformations are used to get some
explicit solutions of the KdVES, which include soliton, rational,
positon, and negaton solutions.
Key words:
the KdV equation with self-consistent sources; restricted flows; Lax pair; Darboux transformation; soliton solution.
