【摘要】 研究了三阶非线性发展方程的初边值问题的解。采用基于Sinc函数的微分求积法发展了线性化有理逼近方法。通常的配点法不适用于上述三阶问题的求解。本文把提出的方法用于求解KdV方程,取得了良好的效果。更多还原

【Abstract】 This paper deals with the solution of initial-boundary value problems of third-order nonlinear evolution equations.A Linearized and Rational Approximation Method was developed,based on differential quadrature method with Sinc-functions.The Korteweg-de Vries equation well exemplified the application of this method.It proves that this method is of high efficiency and accuracy.更多还原
