Abstract

Let C(1)([0, 1]) be the Banach space of continuously differentiable functions on the closed unit interval [0, 1] equipped with the norm ||f||σ= | f (0)| +|| f ′||, where ||g||= sup{|g(t)| : t ∈ [0, 1]} for g. If T : C(1) ([0, 1]) → C(1) ([0, 1]) is a 2-local real-linear isometry, then T is a surjective real-linear isometry.

C(1)([0, 1]) 上的 2 局部实线性等距

摘要

C (1) ([0, 1]) 为闭单位区间 [0, 1] 上的连续可微函数的 Banach 空间,并配备范数 || || σ = | f (0)| +|| f ′|| , 其中 || || = 支持{| g ( t )| : t ∈ [0, 1]} 对于g。如果T : C (1) ([0, 1]) → C (1) ([0, 1]) 是 2 局部实线性等距,则T是满射实线性等距。
