91Second-order arithmetic — In mathematical logic, second order arithmetic is a collection of axiomatic systems that formalize the natural numbers and sets thereof. It is an alternative to axiomatic set theory as a foundation for much, but not all, of mathematics. The… …
92INTERPRÉTATION — Le terme d’interprétation semble être devenu plus complexe et plus problématique depuis qu’il est entré dans le champ d’une réflexion philosophique et épistémologique sur les sciences de l’homme. Celles ci, en retour, ne manquent pas de… …
93Von Neumann–Bernays–Gödel set theory — In the foundations of mathematics, von Neumann–Bernays–Gödel set theory (NBG) is an axiomatic set theory that is a conservative extension of the canonical axiomatic set theory ZFC. A statement in the language of ZFC is provable in NBG if and only …

95Reverse 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… …
96New Foundations — In mathematical logic, New Foundations (NF) is an axiomatic set theory, conceived by Willard Van Orman Quine as a simplification of the theory of types of Principia Mathematica. Quine first proposed NF in a 1937 article titled New Foundations for …
97Morse–Kelley set theory — In the foundation of mathematics, Morse–Kelley set theory (MK) or Kelley–Morse set theory (KM) is a first order axiomatic set theory that is closely related to von Neumann–Bernays–Gödel set theory (NBG). While von Neumann–Bernays–Gödel set theory …
98Readability — is the ease in which text can be read and understood. Various factors to measure readability have been used, such as speed of perception, perceptibility at a distance, perceptibility in peripheral vision, visibility, the reflex blink technique,… …
99Ensemble — Pour les articles homonymes, voir Ensemble (homonymie). En théorie des ensembles, un ensemble désigne intuitivement[1] une collection d’objets (les éléments de l ensemble), « une multitude qui peut être comprise comme un tout » (au sens …
