拉普拉斯方程的柯西问题是不适定问题的一个典型例子,因为它的解对于柯西数据是不稳定的。我们的研究目的是数值求解拉普拉斯方程的柯西问题。然后,我们提出了一种高阶有限差分方法,其中求积点不需要具有格型结构。我们解释我们的方法从指数插值的观点。数值实验表明,本文方法对求解二维拉普拉斯方程的柯西问题是有效的.
The Cauchy problem of the Laplace equation is a typical example of ill-posed problems in the sense that the solution is unstable for the Cauchy data. The aim of our research is to solve the Cauchy problem of the Laplace equation numerically. Then we propose a high order finite difference method in which quadrature points do not need to have a lattice structure. We interpret our method from the viewpoint of the exponential interpolation. From numerical experiments, we confirm that our method is effective for solving the two-dimensional Cauchy problem of the Laplace equation.
