Consider, for instance, the definition of the Riemann integral. A step function on a closed interval is a function of the form: where are real numbers, and denotes the indicator function of the set The space of all step functions on normed by the norm (see Lp space), is a normed vector space which we denote by Define the integral of a step function by: Let denote the space of bounded, piecewise continuous functions on that are continuous from th… If is a metric space, a non-empty subset of and is a Lipschitz continuous function with Lipschitz constant then can be extended to a Lipschitz continuous function with same constant This theorem is also valid for Hölder continuous functions, that is, if is Hölder continuous function with constant less than or equal to then can be extended to a Hölder continuous function with the same constant.

WebTerminology. Whenever a function F : A → R coincides on a subset B of A with a function f : B → R we say “F is an extension of f to A.” Thus the Continuous Extension Theorem can be restated like this: If f is uniformly continuous on a dense subset B of A then f has a unique continuous extension to A. Proof of Uniqueness.

Web$\begingroup$ The key step in the proof of Kirszbraun's theorem involves extending the function to one more point. You write down the conditions on an extension which make the extension have the same Lipschitz constant and show that it is possible to satisfy the conditions. It is easy to make the extension explicit.
