Abstract: This talk concerns the question of what variety of the form X/G, where X is an Abelian variety and G a finite subgroup of Aut(X), is rational. It is motivated by some interesting geometric and dynamical system questions. Most of the work so far concerns the case where X is of the form E^m where E is an elliptic curve, and G is a finite subgroup of Aut(E). I will review the current known results and approaches, and explain why it could be necessary to use computer algebra to resolve the question, and a brief discussion on works in this direction (including my ongoing joint work with Keiji Oguiso).
