Webb5 dec. 2014 · We couch the definition of sΣ-reducibility on structures, describe some properties of sΣ-reducibility, and also exemplify explicitly how to use it. In particular, we consider natural expansions of structures such as Morleyization and Skolemization. Previously, a class of quasiregular structures was defined to be a class of fixed points of … 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.

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.

The axiom of reducibility states that any truth function (i.e. propositional function) can be expressed by a formally equivalent predicative truth function. It made its first appearance in Bertrand Russell’s (1908) Mathematical logic as based on the theory of types, but only after some five years of trial ...
