WebIn mathematical analysis, the uniform norm (or sup norm) assigns to real- or complex -valued bounded functions defined on a set the non-negative number This norm is also called the supremum norm, the Chebyshev norm, the infinity norm, or, when the supremum is in fact the maximum, the max norm.

Can infinity be a supremum? Can it be a maximum?

WebDefinition. A sequence of functions fn: X → Y converges uniformly if for every ϵ > 0 there is an Nϵ ∈ N such that for all n ≥ Nϵ and all x ∈ X one has d(fn(x), f(x)) < ϵ. Uniform convergence implies pointwise convergence, but not the other way around. For example, the sequence fn(x) = xn from the previous example converges pointwise ...
