Abstract
In this talk, the speaker will describe a method of Heegner to solve the equation y2 = x - x3 using modular parametrizations. In particular, Heegner showed that a prime p is a congruent number if it is 5 or 7 modulo 8. Such a work has been generalized by Stephen-Birch and Monsky to products of two primes.
