Propositions accompanying the PhD thesis On monodromy in integrable

Hamiltonian systems Nikolay Martynchuk

1. Morse theory can be used to compute Hamiltonian monodromy.

 Chapter 1 2. The Hamiltonian monodromy of an integrable system with a complexity 1 torus action can be computed in terms of the orbits with S1 isotropy.

 Chapter 2 3. Fractional monodromy is naturally dened for Seifert brations. It is determined by the Euler number and the deck group of the bration.

 Chapter 3 4. The results of Chapter 3 on fractional monodromy and parallel transport extend to integrable Hamiltonian sys-tems with complexity 1 torus actions.

5. The notion of scattering monodromy generalizes to non-integrable Hamiltonian systems.

 Chapter 4 6. A proper choice of a reference Hamiltonian is important

for the study of scattering invariants.

 Chapters 45 7. Euler's two-center problem admits two reference Kepler Hamiltonians. For such reference Hamiltonians, there are non-trivial scattering invariants.

 Chapter 5 8. Man in other people is man's soul.

(Context of integrable systems) In the context of integrable sys- tems the function H is given by the Hamiltonian of the system or another first integral, while the circle action

Recall also that in a neighborhood of the focus-focus singular fiber there exists a Hamiltonian circle action that is free outside the fixed focus-focus points; see Theorem 1.3.3.

In particular, we show that fractional monodromy can be described in terms of the Euler number of an appropriately chosen Seifert fibration and that this number can be computed in

What has been missing until now for scattering monodromy, is a definition which makes an explicit connection to scattering theory and which is applicable to general scattering
