摘要
§1.引言 本文介绍解二阶椭圆本征值问题的有限元插值校正方法.理论分析和数值实验都表明,此方法具有低代价和高精度的特点.这个方法是超收敛和迭代伽略金法的思想相结合的产物。
For quasilinear elliptic boundary value problems, finite element correction schemes withhigher order accuracy than the basic finite element method are proposed. Further, these sche-mes work on a fixed mesh of width h and only one nonlinear system and one linear systemhave to be solved.
