It is concerned with the parts of real analysis and functional analysis that can be carried out in a computable manner. See the history of this page for a list of all contributions to it. In mathematics and computer sciencecomputable analysis is the study of mathematical analysis from the perspective of computability theory.

The equality relation on computable real numbers is not computable, but for unequal computable real numbers the order relation is computable.

Kleene’s second partial combinatory algebra. This means that in analyssis context of analysis a computable function should be an algorithm that successively reads in natural numbers from a possibly infinite list specifying an input to ever higher accuracy and accordingly outputs a result as incrementally as an infinite list. The field is closely related to constructive analysis and numerical analysis.

Concrete examples with an eye towards applications in computable physics are discussed in section 2 of. Bishop seth-set. Constructivism mathematics Computability theory Computable analysis. Last revised on March 3, at Computable real functions map computable real numbers to computable real numbers.

Jaap van OostenRealizability: Weihrauc this is captured by continuous functions on quotient spaces of Baire space computability and goes by the name Type Two Theory of Effectivity or similar. The computable real numbers form a real closed field Weihrauchp. Write AdmRep AdmRep for the category of admissible representations in this sense, and continuously realizable and hence continuous functions between these. In implementations this is essentially what is known as exact real computer arithmetic.
