摘要：In this talk, we report an interesting integrable equation that has both solitons and kink solutions. The integrable equation we study is derived from the negative KdV hierarchy and could be transformed to theCamassa-Holm equation through a gauge transform. The Lax pair of the equation is derived to guarantee its integrability, and furthermore the equation is shown to have classical solitons, periodic soliton and kink solutions. Relations to other well-known systems are also mentioned. The multi-solitons and multi-kink solutions are discussed through Darboux transformation.
