Constructivism mathematics Computability theory Computable analysis. Mathematically 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. From Wikipedia, the free encyclopedia. Jaap van OostenRealizability: See also at effective topological space.
In Type Two Theory of Effectivity for computable analysis see Weihrauch 00 one considers the following definition:. Views Read Edit View history.
A computable function is often taken to be one that acts on the natural numbers a partial recursive function? Retrieved from ” https: Every computable real function is continuous Weihrauchp. Klaus WeihrauchComputable Analysis. The equality relation on computable real numbers is not computable, but for unequal computable real numbers the order relation is computable.

Computable real functions map computable real numbers to computable real numbers. Type Two Theory of Effectivity. Kleene’s second partial combinatory algebra. Kleene’s first partial combinatory algebra.
The computable real numbers form a real closed field Weihrauchp. Computable numbers are the real numbers that can be computed to within any analgsis precision seihrauch a finite, terminating algorithm. This page was last edited on 2 Mayat Write AdmRep AdmRep for the category of admissible representations in this sense, and continuously realizable and hence continuous functions between these. Some standard classes of examples with an eye towards applications in computable physics are discussed in Weihrauch-Zhong 02, def.
They are also known as the recursive numbers or the computable reals. Under the above inclusion, all complete separable metric spaces are in AdmRep AdmRep.
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. Kleene’s first algebraKleene’s second algebra.
Bishop seth-set. In implementations this is essentially what is known as exact real computer arithmetic. Last revised on March 3, at This site is running on Instiki 0.
See the history of this page for a list of all contributions to it. It is concerned with the parts of real analysis and functional analysis that can be carried out in a computable analyxis.
