积分方程本征值问题的外推方法

Extrapolation method for eigenvalue problem of integral equation

以积分方程本征值问题的外推方法改进第二类Fredholm积分方程本征值的数值解—有限元解的精度问题 .利用Richardson外推的方法对本征值的有限元解外推 。

The accuracy of numerical solution—finite element solution of the eigenvalue of second kind Fredholm integral equation is improved by the extrapolation method.Super convergent approximation of finite element solution of eigenvalue can be obtained by Richardson extrapolation method.
