Kleene’s first algebraKleene’s second algebra. Kleene’s second partial combinatory algebra. Type Two Theory of Effectivity. A computable function is often taken to be one that acts on the natural numbers a partial recursive function? This means that in this 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 equality relation on computable real numbers is not computable, but for unequal computable real numbers the order relation is computable.

Concrete examples with an eye towards applications in computable physics are discussed in section 2 of. Computable numbers are the real numbers that can be computed to within any desired precision by a finite, terminating algorithm.

Under the above inclusion, all complete separable metric spaces are in AdmRep AdmRep. The field is closely related to constructive analysis and numerical analysis. In implementations this is essentially what is known as exact real computer arithmetic. See also at effective topological space. It is concerned with the parts of real analysis and functional analysis that can be carried out in a computable manner. The computable real numbers form a real closed field Weihrauchp.

Bishop seth-set. Write AdmRep AdmRep for the category of admissible representations in this sense, and continuously realizable and hence continuous functions between these. From Wikipedia, the free encyclopedia. Every computable real function is continuous Weihrauchp.


Mathematically this is captured by continuous functions on weihrzuch spaces of Baire space computability and goes by the name Type Two Theory of Effectivity or similar. Computable real functions map computable real numbers to computable real numbers.
