ABC implies no "Siegel Zeroes'' for L-functions of characters with negative discriminant (with Harold Stark)
Inventiones Mathematicae, 139 (2000), 509-523.

We prove that the uniform abc-conjecture for number fields implies that there are no Siegel zeros for L-function of quadratic characters (d/.), by studying the singular moduli that give rise to solutions of j(τ)=γ2(τ)3=γ3(τ)2+1728.

An upper bound on the least inert prime in a real quadratic field (with Richard Mollin and Hugh C. Williams)
Canadian Journal of Mathematics, 52 (2000), 369--380.

We show that for every fundamental discriminant D>3705 there is a prime p<D/2 for which (D/p)=1.

Zeros of Fekete polynomials (with Brian Conrey, K. Soundararajan and Bjorn Poonen)
Annales de l'Institut Fourier (Grenoble), 50 (2000), 865--889.

We show that there is a constant c(12,1) such that cp zeros of the pth Fekete polynomial lie on the unit circle

The least common multiple and lattice points on hyperbolas (with Jorge Jiménez-Urroz)
Quarterly Journal of Mathematics (Oxford), 51 (2000), 343--352.

We bound from below the lcm of k integers from a short interval. This is then used to bound the length of any arc of the hyperbola xy=N which contains k lattice points.
