Galois actions on torus-invariant curves of toric surfaces

We are interested in studying the actions of the absolute Galois group on curves on varieties. Toric surfaces form an instructive class of examples since they are geometrically well-understood, and it is natural to study torus-invariant curves here. In this talk I will describe upper bounds on the Galois actions, and ongoing work regarding the inverse problem.
