81Groupe des diviseurs — Diviseur (géométrie algébrique) Les Diviseurs de Weil et de Cartier sont des outils de la géométrie algébrique. En géométrie algébrique, comme en analyse complexe, ou en géométrie arithmétique, les diviseurs forment un groupe qui permet de saisir …
82Covering space — A covering map satisfies the local triviality condition. Intuitively, such maps locally project a stack of pancakes above an open region, U, onto U. In mathematics, more specifically algebraic topology, a covering map is a continuous surjective… …
83Egyptian mathematics — refers to the style and methods of mathematics performed in Ancient Egypt.IntroductionEgyptian multiplication and division employed the method of doubling and halving (respectively) a known number to approach the solution. The method of false… …
84Finite field — In abstract algebra, a finite field or Galois field (so named in honor of Évariste Galois) is a field that contains only finitely many elements. Finite fields are important in number theory, algebraic geometry, Galois theory, cryptography, and… …
85Ratio — This article is about the mathematical concept. For the Swedish institute, see Ratio Institute. For the academic journal, see Ratio (journal). For the philosophical concept, see Reason. For the legal concept, see Ratio decidendi. The ratio of… …
86Divisor — Der Begriff des Divisors spielt in der Algebraischen Geometrie und der Komplexen Analysis eine wichtige Rolle bei der Untersuchung Algebraischer Varietäten bzw. Komplexer Mannigfaltigkeiten und der darauf definierten Funktionen. Unterschieden… …
87Integral domain — In abstract algebra, an integral domain is a commutative ring that has no zero divisors,[1] and which is not the trivial ring {0}. It is usually assumed that commutative rings and integral domains have a multiplicative identity even though this… …
88Model theory — This article is about the mathematical discipline. For the informal notion in other parts of mathematics and science, see Mathematical model. In mathematics, model theory is the study of (classes of) mathematical structures (e.g. groups, fields,… …
89Grassmannian — In mathematics, a Grassmannian is a space which parameterizes all linear subspaces of a vector space V of a given dimension. For example, the Grassmannian Gr 1( V ) is the space of lines through the origin in V , so it is the same as the… …
90Nakayama lemma — In mathematics, more specifically modern algebra and commutative algebra, Nakayama s lemma also known as the Krull–Azumaya theorem[1] governs the interaction between the Jacobson radical of a ring (typically a commutative ring) and its finitely… …
