Abstract:
Boston and Jones studied the action of the absolute Galois group on the tree of iterated preimages of a point under a rational map, phrased in terms of arboreal Galois representations. We extend this to examining the action of Galois on orbits with respect to dynamical correspondences, and survey some recent results.
