摘要
利用压缩映射的非线性二择一性质,得到了Banach空间中压缩映射的若干新不动点定理,从而推广了著名的压缩映射Altman定理、Roth定理和Petryshyn定理.
In this paper, by means of nonlinear alternative for contraction mappings, some new fixed point theorems of contraction mappings are obtained. As a result, the famous Altman's theorem, Roth's theorem and Petryshyn theorem for such class of mappings are generalized.
