摘要:

首先导出了一类可积的变形短脉冲方程族及其Lax表示。然后,我们集中讨论了可积变形短脉冲方程(IDSPE)的解。通过提出一个广义的互逆变换,得到了一个新的可积变形sine-Gordon方程(IDSGE)及其Lax表示.给出了IDSGE的多孤子解、正子解和正子解以及IDSPE的N-圈孤子解、N-正子解和N-圈孤子解。在约化情形下,得到了短脉冲方程的新的N-位置解和N-非线性解。

英文摘要:

We first derive an integrable deformed hierarchy of short pulse equation and their Lax representation. Then we concentrated on the solution of integrable deformed short pulse equation (IDSPE). By proposing a generalized reciprocal transformation, we find a new integrable deformed sine-Gordon equation (IDSGE) and its Lax representation. The multisoliton solutions, negaton solutions and positon solutions for the IDSGE and the N-loop soliton solutions, N-negaton and N-positon solutions for the IDSPE are presented. In the reduced case the new N-positon solutions and N-negaton solutions for short pulse equation are obtained.
