摘    要:主要讨论了一类二阶半线性抛物型方程,研究它在半离散下的Galerkin协调有限元法,借用Riesz投影的性质和其他一些新的估算方法,最后得到了真解和近似解之间在L^2范数下的误差估计.

关 键 词:抛物型方程  半线性  半离散  Galerkin法  误差估计

Abstract:A type of second-order semi-linear parabolic equation was discussed.The Galerkin finite element methods under the semi-discrete situation for the discussed problem were researched.By means of the Riesz projection and other new methods for calculation and estimation,some error estimates in L2 between the real solution and the approximate solution were obtained.
Keywords:parabolic equations  semi-linear  semi-discrete  Galerkin method  error estimation
