Error Estimation for Finite Element Methods of Fourth Order Nonlinear Singular Parabolic Problems
【摘要】 考虑了一类四阶非线性奇异抛物方程,给出了其变分问题及半离散和全离散格式;给出了半离散解的加权L2模及加权H2模误差估计;然后又给出了全离散解即C-N方法的加权L2模误差估计.
【Abstract】 A class of fourth order nonlinear boundary problems with singular coefficients is considered.Its variational problem and semi-discrete and fully discrete formulation are given.The weighted L2 norm and the weighted H2 norm error estimations for semi-discrete problems are obtained.Meantime,an error estimation in weighted L2 norm for C-N fully-discrete scheme is obtained.
