Edit Recursion theory.
Kripke-Platek set theory is closely related to generalized recursion theory.
Main article: Recursion theory.
Recursion theory Recursion Recursion(computer science).
An important subfield of recursion theory studies algorithmic unsolvability;
Recursion theory also includes the study of generalized computability and definability.
The system of Kripke- Platek set theory is closely related to generalized recursion theory.
In recursion theory, 0 can be used to denote the Turing degree of the partial computable functions.
Priority arguments have been employed to solve many problems in recursion theory, and have been classified into a hierarchy based on their complexity(Soare 1987).
Recursion theory 6.1 Algorithmically unsolvable problems 7 Proof theory and constructive mathematics.
Gödel's incompleteness theorem marks not only a milestone in recursion theory and proof theory, but has also led to Löb's theorem in modal logic.
Classical recursion theory focuses on the computability of functions from the natural numbers to the natural numbers.
Mathematical logic is often divided into the subfields of set theory, model theory, recursion theory, proof theory, and constructive mathematics.
Generalized recursion theory extends the ideas of recursion theory to computations that are no longer necessarily finite.
Mathematical logic is an extension of symbolic logic into other areas, in particular to the study of model theory, proof theory, set theory, and recursion theory.
Recursion theory originated in the 1930s, with work of Kurt Gödel, Alonzo Church, Rózsa Péter, Alan Turing, Stephen Kleene, and Emil Post.
Invention of the central combinatorial object of recursion theory, namely the Universal Turing Machine, predates and predetermines the invention of modern computers.
Recursion theory includes the study of generalized notions of this field such as arithmetic reducibility, hyperarithmetical reducibility and a-recursion theory, as described by Sacks(1990).
Remarkably, the invention of the central combinatorial object of recursion theory, namely the Universal Turing Machine, pre-dates and pre-determines the invention of modern computers.
Today recursion theory is mostly concerned with the more refined problem of complexity classes-when is a problem efficiently solvable?
There are uncountably many sets that are not recursively enumerable, andthe investigation of the Turing degrees of all sets is as central in recursion theory as the investigation of the recursively enumerable Turing degrees.
The basic questions addressed by recursion theory are"What does it mean for a function on the natural numbers to be computable?
His work had started logic on this course of clarification; the need to understand Gödel's work then led to the development of recursion theory and then mathematical logic as an autonomous discipline in the 1930s.
Computable and uncomputable sets==Recursion theory originated in the 1930s, with work of Kurt Gödel, Alonzo Church, Alan Turing, Stephen Kleene and Emil Post.
Recursion theory in mathematical logic has traditionally focused on relative computability, a generalization of Turing computability defined using oracle Turing machines, introduced by Turing(1939).
The basic questions addressed by recursion theory are"What does it mean for a function from the natural numbers to themselves to be computable?
Recursion theory, also called computability theory, studies the properties of computable functions and the Turing degrees, which divide the uncomputable functions into sets that have the same level of uncomputability.
The main professional organization for recursion theory is the Association for Symbolic Logic, which holds several research conferences each year.
Today recursion theory is mostly concerned with the more refined problem of complexity classes- when is a problem efficiently solvable?- and the classification of degrees of unsolvability.
According to Rogers,the sets of interest in recursion theory are the noncomputable sets, partitioned into equivalence classes by computable bijections of the natural numbers.
