	Elliptic function - Wikipedia, the free encyclopedia
		Historically, elliptic functions were discovered as inverse functions of elliptic integrals; these in turn were studied in connection with the problem of the arc length of an ellipse, whence the name derives.
		More generally, the study of elliptic functions is closely related to the study of modular functions and modular forms, examples of which include the j-invariant, the Eisenstein series and the Dedekind eta function.
		The derivative of an elliptic function is again an elliptic function, with the same periods.

	Elliptic integral - Wikipedia, the free encyclopedia
		In integral calculus, elliptic integrals originally arose in connection with the problem of giving the arc length of an ellipse and were first studied by Giulio Fagnano and Leonhard Euler.
		Elliptic integrals are often expressed as functions of a variety of different arguments.
		Historically, elliptic functions were discovered as inverse functions of elliptic integrals, and this one in particular: we have F(sn(z;k);k) = z where sn is one of Jacobi's elliptic functions.

	elliptic function
		The elliptic functions can be thought of as analogs of the trigonometric functions (which have only a single period).
		Leading eighteenth-century mathematicians, including Leonhard Euler and Joseph Lagrange, had studied elliptic integrals, such as the integral that gives the arc length of an ellipse; however, these cannot be expressed in terms of the elementary functions (polynomials, exponentials, and trigonometric functions).
		It was the insight of Karl Jacobi, and also of Karl Gauss and Niels Abel, that the inverse functions of elliptic integrals are much easier to study.

	Elliptic functions
		The theory of elliptic functions is one of the highlights of 19th century complex analysis, connected to names such as Gauss, Abel, Jacobi, and Weierstrass.

		Elliptic curves are non-singular, meaning they don't have cusps or self-intersections, and a binary operation can be defined for their points in a natural geometric fashion, thus turning the set of points into an abelian group.
		Elliptic curves can be defined over any field K; the formal definition of an elliptic curve is a non-singular projective algebraic curve over K with genus 1.
		Elliptic curves over finite fields are used in some cryptographic applications as well as for integer factorization.

	Elliptic Curves and Modular Functions
		Modular and elliptic functions are both special cases of the concept of an automorphic function, which is a meromorphic function of 1 or more complex variables defined on a particular complex manifold and invariant under a particular group of analytic transformations (symmetries) of the manifold.
		the modular functions, are essentially the meromorphic functions on D considered as a Riemann surface by its isomorphism with H/ We have stressed this idea of symmetry because of the way it relates the analytic and geometric properties of an object like a Riemann surface to the algebraic properties of a group.
		Thus the elliptic functions are essentially the automorphic functions on the extended complex plane corresponding to the group of translations by two non-collinear values.

	A summary of the definitions and properties of the Jacobian elliptic functions
		The 12 Jacobian elliptic functions are denoted by two letters taken from the quartet s, c, d, n and may be classified into four groups, each with three members, according to the second letter of the function's name.
		The most popular Jacobian elliptic functions is a copolar trio of sine amplitude elliptic function - sn(x,k), cosine amplitude elliptic function - cn(x,k), and delta amplitude elliptic function - dn(x,k).
		The functions sn(x,k), cn(x,k), and dn(x,k) are real valued when their argument is real, and modulus k is either real or purely imaginary.

		Two functions Ns and Ss are created to help in the study because of the complexity involved.
		To accomplish this task, we construct two functions Ns and Ss, which represent the normalized, and “smoothed” sums respectively of ap ‘s defined as p+1 minus the number of solutions modulo p, where p is a prime.
		Moreover, in the case of elliptic curves, deep properties of the curve can be revealed as a result of the properties of the Riemann zeta function and Dirichlet L-functions.

	Open Questions: Elliptic Curves and Modular Forms
		The subject of elliptic curves is a lot like a major city, in which many highways and railroad lines converge, the airport serves as a hub of major airlines, and a seaport connects with important inland waterways.
		It follows that all elliptic functions are of the form g(℘(z)) + ℘′(z)h(℘(z)), where g(t) and h(t) are quotients of polynomials in the indeterminate t.
		Now, we have already seen that an elliptic curve as a complex torus is essentially determined by the period lattice of the &weierp; function that parameterizes the curve.
