Notation: A ≤ M B iff language A is mapping reducible to language B. Note that we reduce languages, not machines. Interesting exercise: Show ≤ M is reflexive and transitive, but not antisymmetric.

In computability theory, many reducibility relations (also called reductions, reducibilities, and notions of reducibility) are studied. They are motivated by the question: given sets $${\displaystyle A}$$ and $${\displaystyle B}$$ of natural numbers, is it possible to effectively convert a method for deciding … Visa mer A reducibility relation is a binary relation on sets of natural numbers that is • Reflexive: Every set is reducible to itself. • Transitive: If a set $${\displaystyle A}$$ is reducible to a set $${\displaystyle B}$$ and $${\displaystyle B}$$ is … Visa mer • Stanford Encyclopedia of Philosophy: Recursive Functions Visa mer The strong reducibilities include • One-one reducibility: $${\displaystyle A}$$ is one-one reducible to $${\displaystyle B}$$ if there is a computable one-to-one function Visa mer Although Turing reducibility is the most general reducibility that is effective, weaker reducibility relations are commonly studied. These reducibilities are related to the relative … Visa mer Webb12 nov. 2014 · Since each of the higher-level sciences is according to our criterion presumably also directly reducible to physics, reducibility turns out to be an asymmetric and transitive relation.

"Webb21 maj 1996 · Philosophers soon followed Ludwig Wittgenstein (1922) and disputed the idea that these additional axioms, the axioms of reducibility and infinity, are really logical truths, and so denied that the logicist program of reducing arithmetic to logic was any more successful than Frege’s attempt had been.

WebbThe theory has an infinite number of stages of reducibility. We specify conditions on the base manifold under which the covariant quantization of the system can be performed unambiguously.
