71Asymptote — For other uses, see Asymptote (disambiguation). The graph of a function with a horizontal, vertical, and oblique asymptote …
72Modular group — For a group whose lattice of subgroups is modular see Iwasawa group. In mathematics, the modular group Γ is a fundamental object of study in number theory, geometry, algebra, and many other areas of advanced mathematics. The modular group can be… …
73Space group — In mathematics and geometry, a space group is a symmetry group, usually for three dimensions, that divides space into discrete repeatable domains. In three dimensions, there are 219 unique types, or counted as 230 if chiral copies are considered… …
74Clifford algebra — In mathematics, Clifford algebras are a type of associative algebra. They can be thought of as one of the possible generalizations of the complex numbers and quaternions.[1][2] The theory of Clifford algebras is intimately connected with the… …
75Congruence relation — See congruence (geometry) for the term as used in elementary geometry. In abstract algebra, a congruence relation (or simply congruence) is an equivalence relation on an algebraic structure (such as a group, ring, or vector space) that is… …
76Split-complex number — A portion of the split complex number plane showing subsets with modulus zero (red), one (blue), and minus one (green). In abstract algebra, the split complex numbers (or hyperbolic numbers) are a two dimensional commutative algebra over the real …
77Géométrie projective — En mathématiques, la géométrie projective est le domaine de la géométrie qui modélise les notions intuitives de perspective et d horizon. Elle étudie les propriétés inchangées des figures par projection. Sommaire 1 Considérations historiques 2… …
78Riemann surface — For the Riemann surface of a subring of a field, see Zariski–Riemann space. Riemann surface for the function ƒ(z) = √z. The two horizontal axes represent the real and imaginary parts of z, while the vertical axis represents the real… …
79Diviseur (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 la nature d un schéma (une… …
