Abstract:
For $A_t(x) = f(x) - t g(x)$, we consider the set $\{ \sum _{A_t(\alpha ) = 0} h(\alpha ) : t \in \overline {\mathbb {Q}} \}$. The polynomials $f(x), g(x)$ are in $\mathbb {Z}[x]$, with only mild restrictions, and $h(\alpha )$ is the Weil height of $\alpha$. We show that this set is dense in $[d, \infty )$ for some effectively computable limit point $d$.References
