Boris Kruglikov "Vanishing of topological entropy for certain integrable Hamiltonian systems".

By a request I start with a general discussion of various entropies arising in physics, information theory and dynamics.

Then I review what is known about entropies of Hamiltonian systems, esp. integrable ones (see e.g. here, here or here). Discuss what is obvious and what is not.

And then go to a couple of joint theorems with V.Matveev (Freiburg).
