摘要
讨论了一类发展方程——线性抛物型方程的窄四边形元逼近方法,导出了相应的半离散格式和全离散格式,并通过一些新的技巧,得到了相应的误差估计.
An approximation method of narrow quadrilateral finite element for a class of nonstationary equations—linear parabolic equations is discussed.If se-midiserete form and fulldicrete form of parabolic equations are given,optimal error estimates are obtained by using some new approaches.
