Wahlquist和Estabrook的延拓结构理论是研究(1+1)维可积系统的强有力的工具.利用该理论分析和构造可积的各项异性的修正海森堡铁磁链方程,并给出了它的Lax表示.
The prolongation structure theory proposed by Wahlquist and Estabrook is a very effective tool in the analysis of(1+1)-dimensional integrable systems.The anisotropic modified Heisenberg ferromagent equation is investigated by using prolongation structure theory and Lax representation is given.
