Elliptic Curves are related to the solutions to equations y^2 = x^3 + A x + B in the field of rationals, algebraic extensions of the rationals, p-adic rational numbers, or a finite field. They are used in factorization of integers and also played a role in the recent resolution of the conjecture known as Fermat's Last Theorem.
Please submit only sites of theoretical content in the subject of elliptic curves and modular forms. This may include applications of such theory, such as their usage in primality proving, factorization, and cryptography - however in these cases consider carefully whether the site is more suited to those categories in the Open Directory Project. Software programs and tables should be submitted to the appropriate subcategory.
