Theory of reducibility
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. Webbto make sure we're all together on understanding how reducibility works. OK, so the concept of reducibility is that we say one problem is reducible to another, say A …
Theory of reducibility
Did you know?
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 Webb摘要： Reducibility is an essential characteristic of oxide catalysts in oxidation reactions following the Mars–van Krevelen mechanism. A typical descriptor of the reducibility of an oxide is the cost of formation of an oxygen vacancy, which measures the tendency of the oxide to lose oxygen or to donate it to an adsorbed species with consequent change in …
WebbIn this paper we study the complete reducibility of representations of infinite-dimensional Lie algebras from the perspective of representation theory of vertex algebras. WebbThe most serious alternative to this reducibility thesis of the Unity of Science movement is the theory of emergent evolution, according to which life or mind (or both) are genuinely novel forms of reality that could not possibly have been derived from, or predicted by, any laws or theories of the lower or earlier levels of existence.

The axiom of reducibility states that any truth function (i.e. propositional function) can be expressed by a formally equivalent predicative truth function.
