Abstract

Given a smooth curve C/QC/\mathbb{Q} with genus 2\geq 2, we know by Faltings' Theorem that C(Q)C(\mathbb{Q}) is finite. Here we ask the reverse question: given a finite set of rational points SPn(Q)S\subseteq \mathbb{P}^n(\mathbb{Q}), does there exist a smooth curve C/QC/\mathbb{Q} contained in Pn\mathbb{P}^n such that C(Q)=SC(\mathbb{Q})=S? We answer this question in the affirmative by providing an effective algorithm for constructing such a curve.
