Topology change of levels sets in Morse theory

Andreas Knauf, Nikolay Martynchuk

Classical Morse theory proceeds by considering sublevel sets f−1(−∞,a] of a Morse function f:M→R, where M is a smooth finite-dimensional manifold. In this paper…

Hamiltonian monodromy and Morse theory

Nikolay Martynchuk, Henk W. Broer, Konstantinos Efstathiou

We show that Hamiltonian monodromy of an integrable two degrees of freedom system with a global circle action can be computed by applying Morse theory to the Hamiltonian of the sys…
