本文从紧集的ε覆盖角度重新审视一阶Fredholm积分方程的正则化方法,探讨通过限制可接受解集的a priori全局界来截断形式展开式的方法。

摘要:

一阶Fredholm积分方程是Hadamard意义下典型的不良好问题。如果积分算子是自伴随的且具有特征函数集,则可通过特征函数展开式得到形式解。一种可能的正则化方法是通过限制可接受解集的a priori全局界来截断此形式展开式。本文从紧集的ε覆盖角度重新审视各种可能的截断方法。

英文摘要:

The Fredholm integral equations of the first kind are a classical example of ill-posed problem in the sense of Hadamard. If the integral operator is self-adjoint and admits a set of eigenfunctions, then a formal solution can be written in terms of eigenfunction expansions. One of the possible methods of regularization consists in truncating this formal expansion after restricting the class of admissible solutions through a-priori global bounds. In this paper we reconsider various possible methods of truncation from the viewpoint of the $\varepsilon$-coverings of compact sets.
