摘要:

本文利用指数B样条基函数集开发了一种置信方法,用于解决Gardner方程的初值边界值问题。Gardner方程包含两个非线性项,即二次和三次项。通过方程的降阶,得到耦合的PDE系统,使指数B样条得以实现。该系统通过Crank-Nicolson隐式方法进行时间积分。通过计算离散最大误差范数和观察模拟结束时守恒律的绝对相对变化,验证了该方法的有效性。

英文摘要:

The exponential B-spline basis function set is used to develop a collocation method for some initial boundary value problems (IBVPs) to the Gardner equation. The Gardner equation has two nonlinear terms, namely quadratic and cubic ones. The order reduction of the equation is resulted in a coupled system of PDEs that enables the exponential B-splines to be implemented. The system is integrated in time by Crank-Nicolson implicit method. The validity of the method is investigated by calculating the discrete maximum error norm and observing the absolute relative changes of the conservation laws at the end of the simulations.
