摘要: 我们利用K-dv方程阐明非线性波动方程类五大特色:1)逆散射方法、2)Bäcklund变换、3)、守恒律、4)N-孤立子解、5)完全可积Hamilton系统之间的内在联系。

Abstract: We make use of the K-dv equation to clarify the relation-shios among the five characteristics for a class of nonlinear wave equatioos.It is shown that (1) Inverse scatering transform (IST);(2) Böcklund transformation (BT);(3)N-soliton solutions (N-SS);(4)a unite or an infinite number of conservation laws (CL) and (5)a complete integrable Hamilton system (HS) are closely related.The scheme of the presentation is shown in the following figure
