Congruent Numbers and Heegner Points

Abstract

Mohammed Ben Alhocain, in an Arab manuscript of the tenth century, stated that the principal object of the theory of rational right triangles is to find a square which when increased or diminished by a certain number mm becomes a square (see Dickson). In modern language, this object is to find a rational point of infinite order on the elliptic curve my2=x3xmy^2=x^3-x. Heegner constructed (see also Monsky) such rational points in the case that mm are primes congruent to 5, 7 modulo 8 or twice primes congruent to 6 modulo 8. We extend Heegner's result to integers mm with many prime divisors.
