【摘要】:借助吴方法和Maple符号计算系统,利用变分导数方法和乘子策略构造等离子物理中的一类非线性Compacton ZK方程的守恒律.首先,基于变分导数方法确定ZK方程的乘子集;其次,利用乘子策略推出ZK方程的守恒律.值得一提的是:导出ZK方程的无穷多个乘子及其对应的守恒律,这对揭示该方程的相关属性方面具有重要意义.
[Abstract]:The conservation laws of a class of nonlinear Compacton ZK equations in plasma physics are constructed by the variational derivative method and the multiplier strategy with the help of Wu's method and the Maple symbolic computing system. Firstly, the multiplicator set of the ZK equation is determined based on the variational derivative method, and the second is the conservation law of the nonlinear Compacton ZK equation in plasma physics. The conservation law of ZK equation is derived by means of multiplier strategy. It is worth mentioning that infinitely many multipliers of ZK equation and their corresponding conservation laws are derived, which is of great significance in revealing the related properties of the equation.
