High Quality Content by WIKIPEDIA articles! In number theory, the Mordell conjecture stated a basic result regarding the rational number solutions to Diophantine equations. It was eventually proved by Gerd Faltings in 1983, about six decades after the conjecture was made; it is now known as Faltings' theorem. Suppose we are given an algebraic curve C defined over the rational numbers (that is, C is defined by polynomials with rational coefficients), and suppose further that C is non-singular (in this case that condition isn't a real restriction). How many rational points (points with rational coordinates) are on C? The answer depends upon the genus g of the curve. As is common in number theory, there are three cases: g = 0, g = 1, and g > 1. The g = 0 case has been understood for a long time; Mordell solved the g = 1 case, and conjectured the result when g > 1.
