关于F-空间中保持距离相等的映射

On maps which preserve equality of distance in F-spaces

Dongni Tan

摘要:

为了推广Mazur-Ulam和Vogt的结果,我们证明了在没有满射条件的情况下,两个F-空间之间保持距离相等且T(0)=0的映射T是线性的.然后,作为特殊情况,线性等距通过其范围的简单性质来表征。

英文摘要:

In order to generalize the results of Mazur-Ulam and Vogt, we shall prove that any map T which preserves equality of distance with T(0)=0 between two F-spaces without surjective condition is linear. Then, as a special case linear isometries are characterized through a simple property of their range.
