Abstract

We find all elliptic curves defined over ℚ that have a rational point of order N, N ≥ 4, and whose conductor is of the form paqb, where p, q are two distinct primes and a, b are two positive integers. In particular, we prove that Szpiro's conjecture holds for these elliptic curves. © 2013 American Mathematical Society.
