Preperiodic points for families of rational map

Dragos Ghioca, Liang-Chung Hsia, Thomas J. Tucker

Let X be a smooth curve defined over the algebraic numbers, let a,b be algebraic numbers, and let f_l(x) be an algebraic family of rational maps indexed by all l in X. We study whe…

Torsion points in families of Drinfeld modules

Dragos Ghioca, Liang-Chung Hsia

Let $Φ^{ł}$ be an algebraic family of Drinfeld modules defined over a field $K$ of characteristic $p$ , and let $\bfa,\bfb\in K[ł]$. Assume that neither $\bfa(ł)$ nor $\bfb(ł)$ is a t…
