【摘要】:借助吳方法和Maple符號計算系統(tǒng),利用變分導(dǎo)數(shù)方法和乘子策略構(gòu)造等離子物理中的一類非線性Compacton ZK方程的守恒律.首先,基于變分導(dǎo)數(shù)方法確定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:導(dǎo)出ZK方程的無窮多個乘子及其對應(yīng)的守恒律,這對揭示該方程的相關(guān)屬性方面具有重要意義.
[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.
