Abstract
Classical fractons - classical particles obeying multipole conservation laws - manage to evade two well known folk theorems about Hamiltonian systems. The first is that Liouville's theorem forbids attractors and second that the Mermin-Wagner theorem forbids the breaking of a continuous translational symmetry in d=1 and 2 at finite energy densities. I will explain how they do this via Machian dynamics and how one can understand these results.
