摘要: 利用拟谱方法研究了非线性Cahn-Hilliard方程解的近似, 分析了半离散与全离散近似解的收敛性和稳定性, 并给出收敛速度的估计. 同时还讨论了半离散问题解的爆破现象.

Abstract: We studied the numerical approximation to Cahn-Hilliard equation with pseudo-spectral method. We proved the convergence and the st ability of the semi-discrete and the full-discrete soltions to the real solution and figured out the corresponding rate of the convergence. Finaly, we obtained the blow-up phenomena of the semi-discrete problem’s solution.

Key words: pseudo-spectral method, interpolation operator, blow-up
