摘　　要：在研究Banach不动点定理的基础上,讨论非扩展映射的不动点问题,证明了严格非扩展映射的象是X中的列紧集时,它必有惟一的不动点.Based on studying the Banach fixed-point theorem, the problem on fixed-point of non-extended mapping is discussed. Obtained that the strictly non-extended mapping must have only one fixed-point when its image is a sequentially compact set of X.

关 键 词：压缩映射 BANACH不动点定理 (严格)非扩展映射
