Uniform norm

(重定向自Uniform metric)

In mathematical analysis, the uniform norm (or sup norm) assigns to real- or complex-valued bounded functions f defined on a set S the non-negative number

This norm is also called the supremum norm, the Chebyshev norm, or the infinity norm. The name "uniform norm" derives from the fact that a sequence of functions \{f_n\} converges to f under the metric derived from the uniform norm if and only if f_n converges to f uniformly.
