61Rational homotopy theory — In mathematics, rational homotopy theory is the study of the rational homotopy type of a space, which means roughly that one ignores all torsion in the homotopy groups. It was started by Dennis Sullivan (1977) and Daniel Quillen (1969) …

63Circumscription (logic) — Not to be confused with circumscribe. Circumscription is a non monotonic logic created by John McCarthy to formalize the common sense assumption that things are as expected unless otherwise specified. Circumscription was later used by McCarthy in …

65Constructible universe — Gödel universe redirects here. For Kurt Gödel s cosmological solution to the Einstein field equations, see Gödel metric. In mathematics, the constructible universe (or Gödel s constructible universe), denoted L, is a particular class of sets… …
66Moral realism — This article is about moral realism in the robust sense. For moral realism in the moderate or minimal sense, see Moral universalism. Moral realism is the meta ethical view which claims that: Ethical sentences express propositions. Some such… …
67Countable set — Countable redirects here. For the linguistic concept, see Count noun. Not to be confused with (recursively) enumerable sets. In mathematics, a countable set is a set with the same cardinality (number of elements) as some subset of the set of… …
68Enriques–Kodaira classification — In mathematics, the Enriques–Kodaira classification is a classification of compact complex surfaces into ten classes. For each of these classes, the surfaces in the class can be parametrized by a moduli space. For most of the classes the moduli… …
69Flip (algebraic geometry) — In mathematics, specifically in algebraic geometry, a flip is a certain kind of codimension 2 surgery operation arising naturally in the attempt to construct a minimal model of an algebraic variety. The minimal model program can be summarised… …
70Closed world assumption — The closed world assumption (CWA) is the presumption that what is not currently known to be true, is false. The same name also refers to a logical formalization of this assumption by Raymond Reiter. The opposite of the closed world assumption is… …
