KdV和mKdV方程的非完整变形及其对称性、族性和可积性

Nonholonomic deformation of KdV and mKdV equations and their symmetries, hierarchies and integrability

Anjan Kundu, R. Sahadevan, L. Nalinidevi

摘要:

本文将KdV方程的可积非完整变形概念推广到mKdV方程,并推广到AKNS系统。对于变形的mKdV方程,我们发现了一个矩阵拉克斯对,一个新的双重可积族和精确的N孤子解显示出不寻常的加速运动。我们证明了变形的KdV和mKdV系统都具有无穷多个广义对称性、守恒量和一个递归算子。

英文摘要:

Recent concept of integrable nonholonomic deformation found for the KdV equation is extended to the mKdV equation and generalized to the AKNS system. For the deformed mKdV equation we find a matrix Lax pair, a novel two-fold integrable hierarchy and exact N-soliton solutions exhibiting unusual accelerating motion. We show that both the deformed KdV and mKdV systems possess infinitely many generalized symmetries, conserved quantities and a recursion operator.
