Abstract:
In 1966, Shanks and Schmid investigated the asymptotic behavior of the number of positive integers less than or equal to $x$ which are represented by the quadratic form $X^2+nY^2$, n greater than or equal to 1. Based on some numerical computations, they observed that the constant occurring in the main term appears to be the largest for $n=2$. In this talk, we discuss a proof of the fact that this constant is actually unbounded as one runs through fundamental discriminants with a fixed number of distinct prime divisors. This is joint work with David Brink and Pieter Moree (MPIM).
