利用基于 WTC 方法的 Kruskal 简化法判别了一类特殊的非线性耦合Jaulent-Miodek 方程在三种情形下具有 Painleve;可积性,一种情形下不具有 Painleve;可积性。尽管Jaulent-Miodek 方程在一种情形下不具有 Painleve;可积性,仍可以通过推广的 Painleve;标准截断展开和 Painleve;非标准截断展开方法求得非线性耦合 Jaulent-Miodek 方程行波形式的精确解。
The Painleve;integrability of a special coupled Jaulent-Miodek equation was studied by using the Kruskal’s simplification of WTC method.The following conclusion was obtained:the Jaulent-Miodek equation is of Painleve; integrability in three cases,and is of no Painleve; integrability in one case.Even though in that case,the equation is of no Painleve;integrability,new exact solutions of the coupled Jaulent-Miodek equation can be constructed by using the Painleve; standard and nonstandard truncation expansion.
