Abstract:

We show that if two complex quadratic polynomials in a single variable each have a coefficient 1, then their product must have a coefficient with absolute value at least $(\sqrt {13}-3)/2$. This is best possible. There is a more natural and classical formulation using heights. We also present some speculations about higher degree involving Littlewood polynomials.
