【摘要】 本文主要讨论Ｆｒｅｃｈｅｔ空间上ε－等距线性算子的等距逼近问题，证明了任意有限维Ｆｒｅｃｈｅｔ空间之间的等距逼近问题都是肯定的；无穷维Ｆｒｅｃｈｅｔ空间（ｓ）空间上的等距逼近问题也是肯定的．更多还原

【Abstract】 Topics on the approximation problem of ε-almost isometric operator by isometric operators in Frechet spaces are present in this paper. The approximation problems of isometric operators between finite dimensional Frechet spaces, or between infinite dimensional Frechet space (s) are affirmative.更多还原
