解二阶椭圆本征值问题的有限元插值校正方法

In this paper, a finite element interpolated correction method for second order elliptic ei-genvalue problems is suggested, and proved to be able to achieve higher accuracy with only a li-ttle arithmetic operation. The method is based mainly on the superconvergence and the iteratedCalerkin method.
