Théorème de Fagin — Le théorème de Fagin est un résultat de théorie de la complexité des algorithmes, montrant l égalité de la classe NP (en) et de la classe des problèmes exprimables en logique du second ordre existentielle, c est à dire en logique du premier… … Wikipédia en Français
Descriptive complexity — is a branch of finite model theory, a subfield of computational complexity theory and mathematical logic, which seeks to characterize complexity classes by the type of logic needed to express the languages in them. For example, PH, the union of… … Wikipedia
Mathematical logic — (also known as symbolic logic) is a subfield of mathematics with close connections to foundations of mathematics, theoretical computer science and philosophical logic.[1] The field includes both the mathematical study of logic and the… … Wikipedia
Second-order logic — In logic and mathematics second order logic is an extension of first order logic, which itself is an extension of propositional logic.[1] Second order logic is in turn extended by higher order logic and type theory. First order logic uses only… … Wikipedia

Descriptive complexity theory — For other uses, see Kolmogorov complexity. Descriptive complexity is a branch of computational complexity theory and of finite model theory that characterizes complexity classes by the type of logic needed to express the languages in them. For… … Wikipedia
Dependence logic — is a logical formalism, created by Jouko Väänänen[1], which adds dependence atoms to the language of first order logic. A dependence atom is an expression of the form , where are terms, and corresponds to the statement that the value of is… … Wikipedia
SNP (complexity) — In computational complexity theory, SNP (from Strict NP) is a complexity class containing a limited subset of NP based on its logical characterization in terms of graph theoretical properties. It forms the basis for the definition of the class… … Wikipedia
NP (complexity) — Diagram of complexity classes provided that P ≠ NP. The existence of problems outside both P and NP complete in this case was established by Ladner.[1] In computational complexity theory, NP is one of the most fundamental complexity classes. The… … Wikipedia
