Tietze Extension Theorem
... Let f be a real-yielding function, let r be a real number, and let X be a set. We say that f is absolutely bounded by r in X if and only if: (Def. 1) For every set x such that x ∈ X ∩ dom f holds |f (x)| ≤ r. Let us mention that there exists a sequence of real numbers which is summable, constant, an ...

The Uniform Continuity of Functions on Normed Linear Spaces
... (Def. 2)(i) X ⊆ dom f, and (ii) for every r such that 0 < r there exists s such that 0 < s and for all x1 , x2 such that x1 ∈ X and x2 ∈ X and kx1 − x2 k < s holds |fx1 − fx2 | < r. The following propositions are true: (1) If f is uniformly continuous on X and X1 ⊆ X, then f is uniformly continuous ...
