112Hilbert's tenth problem — is the tenth on the list of Hilbert s problems of 1900. Its statement is as follows:Given a Diophantine equation with any number of unknown quantities and with rational integral numerical coefficients: To devise a process according to which it… …
113Hypercomputation — refers to various hypothetical methods for the computation of non Turing computable functions (see also supertask). The term was first introduced in 1999 by Jack Copeland and Diane Proudfoot [Copeland and Proudfoot,… …
114Arithmetical hierarchy — In mathematical logic, the arithmetical hierarchy, arithmetic hierarchy or Kleene hierarchy classifies certain sets based on the complexity of formulas that define them. Any set that receives a classification is called arithmetical. The… …
115Reverse mathematics — is a program in mathematical logic that seeks to determine which axioms are required to prove theorems of mathematics. The method can briefly be described as going backwards from the theorems to the axioms. This contrasts with the ordinary… …
116List of mathematical logic topics — Clicking on related changes shows a list of most recent edits of articles to which this page links. This page links to itself in order that recent changes to this page will also be included in related changes. This is a list of mathematical logic …
117Economic model — A diagram of the IS/LM model In economics, a model is a theoretical construct that represents economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified… …
118Limiting recursive — In computability theory, the term limiting recursive (also limit recursive or limit computable) describes sets that are the limit of a sequence of computable sets. Definition A set S is limiting recursive if there is a total computable function g …
119Turing jump — In computability theory, the Turing jump or Turing jump operator, named for Alan Turing, is intuitively described as an operation that assigns to each decision problem X a successively harder decision problem X prime; with the property that X… …
120Numbering (computability theory) — In computability theory a numbering is the assignment of natural numbers to a set of objects like rational numbers, graphs or words in some language. A numbering can be used to transfer the idea of computability and related concepts, which are… …
