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.

摘要
令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 || 女|| σ = | f (0)| +|| f ′|| ∞ , 其中 || 克|| ∞ = 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。
