1Algebraic curve — In algebraic geometry, an algebraic curve is an algebraic variety of dimension one. The theory of these curves in general was quite fully developed in the nineteenth century, after many particular examples had been considered, starting with… …
2Cruciform curve — The cruciform curve, or cross curve is a quartic plane curve given by the equation Cruciform with parameters (b,a) being (1,1) in red; (2,2) in green; (3,3) in blue …
3Forgetting curve — A typical representation of the forgetting curve. The forgetting curve hypothesizes the decline of memory retention in time. A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger… …
4Singular point in a curve — Singular Sin gu*lar (s[i^][ng] g[ u]*l[ e]r), a. [OE. singuler, F. singulier, fr. L. singularius, singularis, fr. singulus single. See {Single}, a.] 1. Separate or apart from others; single; distinct. [Obs.] Bacon. [1913 Webster] And God forbid… …
5ADE classification — The simply laced Dynkin diagrams classify diverse mathematical objects. In mathematics, the ADE classification (originally A D E classifications) is the complete list of simply laced Dynkin diagrams or other mathematical objects satisfying… …
6Resolution of singularities — Strong desingularization of Observe that the resolution does not stop after the first blowing up, when the strict transform is smooth, but when it is simple normal crossings with the exceptional divisors. In algebraic geometry, the problem of… …
7Economic Affairs — ▪ 2006 Introduction In 2005 rising U.S. deficits, tight monetary policies, and higher oil prices triggered by hurricane damage in the Gulf of Mexico were moderating influences on the world economy and on U.S. stock markets, but some other… …
8Canonical bundle — In mathematics, the canonical bundle of a non singular algebraic variety V of dimension n is the line bundle which is the nth exterior power of the cotangent bundle Ω on V. Over the complex numbers, it is the determinant bundle of holomorphic n… …
9Del Pezzo surface — In mathematics, a del Pezzo surface or Fano surface is a two dimensional Fano variety, in other words a non singular projective algebraic surface with ample anticanonical divisor class. They are in some sense the opposite of surfaces of general… …
10Hurwitz's automorphisms theorem — In mathematics, Hurwitz s automorphisms theorem bounds the group of automorphisms, via orientation preserving conformal mappings, of a compact Riemann surface of genus g > 1, telling us that the order of the group of such automorphisms is bounded …
