In mathematics, an elliptic curve is an algebraic curve defined by an equation of the form

y2 = x3 + a x + b,
which is non-singular; that is, its graph has no cusps or self-intersections. (When the characteristic of the coefficient field is equal to 2 or 3, the above equation is not quite general enough to comprise all non-singular cubic curves; see below for a more precise definition.)

If y2 = P(x), where P is any polynomial of degree three or four in x with no repeated roots, then we obtain a nonsingular plane curve of genus one, which is often also called an elliptic curve. Even more generally, an algebraic curve of genus one, for example from the intersection of two three-dimensional quadric surfaces, is called an elliptic curve.

One finds that elliptic curves correspond to embeddings of the torus into the complex projective plane; such embeddings generalize to arbitrary fields, and so it is said that elliptic curves are non-singular projective algebraic curves of genus 1 over a field K, together with a distinguished point defined over K. The natural group structure of a torus manifests itself in a curious geometric way on an elliptic curve; the set of points of the curve form an abelian group.
