摘要:本文介紹了常用的壓縮映射、不動(dòng)點(diǎn)定理的應(yīng)用.在各類方程的求解問題里常轉(zhuǎn)化為求映射的不動(dòng)點(diǎn),首先將原方程適當(dāng)變形使其符合壓縮映射原理的條件,以便應(yīng)用逐次逼近法求得不動(dòng)點(diǎn)即原方程的根. 關(guān)鍵詞:壓縮映射原理;不動(dòng)點(diǎn)定理;逐次迭代法
ABSTRACT:This paper introduces some applications of Contraction mappings and the Banach Fixed-point theorem .Many kinds of equations can be transposed into fixed-point problems. The original equation is transformed so that the principle of contraction can be applied and a successive approximation method can be used to find the fixed-point, which is the solution to the equation. Keywords: Contraction mapping principle; Fixed-point theorem; Method of successive iteration
本文中,我們?cè)诘谝徽聦?duì)壓縮映射及其相關(guān)概念作扼要的介紹;第二章中主要介紹壓縮映射、不動(dòng)點(diǎn)定理的應(yīng)用,主要思想是把所求的方程通過轉(zhuǎn)化,使其具有壓縮映射的形式,再通過壓縮映射的特點(diǎn)對(duì)其進(jìn)行求解.在這里,我們所強(qiáng)調(diào)的是方程變形的手段,一些方程用通常的方法很難求出,但把它轉(zhuǎn)化為具有壓縮映射的條件以后就很容易求解了.
