On the integrability of the n-centre problem
Andreas Knauf, Iskander A. Taimanov
It is known that for centres and positive energies the -centre problem of celestial mechanics leads to a flow with a strange repellor and positive topological entropy…

Integrability of the n-centre problem at high energies
A. Knauf, I. A. Taimanov
It is shown that for generic configuration of the centres at high energy levels the n-centre problem is completely integrable by using integrals of the motion however it…

On the Form Factor for the Unitary Group
Mirko Degli Esposti, Andreas Knauf
We study the combinatorics of the contributions to the form factor of the group U(N) in the large limit. This relates to questions about semiclassical contributions to the form…
