May 8, 2025 · This method computes points in elliptic curves, which are represented by formulas such as y² ≡ x³ + ax + b (mod n) where n is the number to factor. elliptic-curves; Share. This means that There must be faster ways of determining the rank and Mordell-Weil group of an elliptic curve with coefficients, rank, and generators of this size, but the fact that mwrank was able to do it in three weeks might still be an interesting data point about this kind of computation. Not every smooth projective curve of genus 1 corresponds to an elliptic curve, it needs to have at least one rational point! For example, the (desingularization of) the curve deﬁned by . k) is a smooth projective curve of genus 1 (deﬁned over . fact unbounded in such a family? Stiller [14], Shioda [10], and Fastenberg [3] have given examples of elliptic curves over C(t) which have ﬁnite rank over S r∈Z C(t 1/r), and Ulmer [16] gives examples of elliptic curves over k(t) with ﬁnite rank over S n∈Z >0 k(t1/pn) for certain ﬁnite ﬁelds kand primes p. The ranks of elliptic curves over Q The most signi cant thing we know about ris a bound on its average value over all elliptic curves (suitably ordered).
