Action-Angle Duality for a Poisson-Lie Deformation of the Trigonometric I. Marshall |
|||
Аннотация: The property of action-angle duality was first brought to light in a systematic way by Ruijsenaars. The method of Hamiltonian reduction reveals a natural mechanism for how such a phenomenon can arise. I will give a general overview of this and present as a special case the new result, obtained together with László Fehér, referred to in the title. Язык доклада: английский |
