摘要
本文对色散方程ut=auxxx的初边值问题,构造两个绝对稳定的半显式格式,其局部截断 误差为O(τ2+h4+τ2/h2),精度较高.
Two absolute stable and high accuracy semi-explicit difference schemes where r= qt/h3 for solving the initial boundary value problems of the dispersive equation ut = auxxx are constructed. Thc local truncation errors for these difference schemes arc O(t2+ h4+t2/h2)
