Speaker: Robert Vaughan, Penn State

Abstract: We are concerned with which $n$ which can be represented in the form $x^2+zy^2=n$ where $z$ is generally small compared with the size of $n$. We show that almost all $n$ have such a representation with $z<(\log n) (\log\log n)^{3+\delta}$ and that a positive proportion do with $z\ll (\log n)(\log\log n)$. This is joint work with Brandon Hanson.
