An illustration of Action-angle duality arising from Hamiltonian reduction (Ian Marshall, Higher School of Economics, Moscow)

24.01.2018 10:30

I will show how Hamiltonian reduction may often be used to generate pairs of systems in Action-Angle duality with one another, and present an example. This example is a pair of systems of Ruijsenaars type with BCn symmetry. Both systems can be identified as limiting cases of the van Diejen system, and their flows can be shown to be complete by means of the reduction procedure.
