A game-theoretic approach to Hjorth's turbulence theory
Martino Lupini, Department of Mathematics, Caltech,
I will present a short conceptual proof of Hjorth's turbulence theorem in terms of a suitable open game. I will then explain how these ideas can be modified to prove a new dynamical criterion that provides an obstruction to classification by orbits of a CLI-group action. This is joint work with Aristotelis Panagiotopoulos.
