Pelayo, Álvaro2026-01-262026-01-2620230166-864110.1016/j.topol.2023.108577https://hdl.handle.net/20.500.14352/131018We first give a glimpse of finite dimensional classical integrable Hamiltonian systems from the point of view of symplectic geometry and briefly discuss their quantum counterparts, with an emphasis on recent progress on inverse spectral geometry. Then we propose several open problems about the geometry, topology and dynamics of these systems. The problems are largely motivated by the works of a number of authors, including Arnold, Atiyah, Colin de Verdière, Delzant, Duistermaat, Eliasson, Fomenko, Guillemin, Kolmogorov, Kostant, Moser and Sternberg.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://doi.org/10.1016/j.topol.2023.108577open accessIntegrable systemSymplectic manifoldHamiltonian systemSpectralEigenvalueOpen problemMomentum mapToric systemSemitoric systemDelzant polytopeModuli spaceMatemáticas (Matemáticas)12 Matemáticas
