Sergyeyev on Dynamical Systems
In the paper
Exact
solvability of superintegrable Benenti systems (arXiv
version)
we established quantum and classical exact solvability for two large
classes of maximally superintegrable Benenti systems in n
dimensions with arbitrarily large natural n
(For the background on superintegrability see here
if necessary).
See also the related paper with Maciej Błaszak, Ziemowit Domański
and Błażej M. Szablikowski
Integrable
quantum Stäckel systems (arXiv version)
and the paper with Pavel Krtouš on quantum integrability for the
Klein-Gordon equation on a class of curved backgrounds
Complete set of commuting symmetry
operators for the Klein-Gordon equation in generalized
higher-dimensional Kerr-NUT-(A)dS spacetimes

Coupling
constant metamorphosis as an integrability-preserving
transformation for general finite-dimensional dynamical systems
and ODEs (arXiv version)
where the multiparameter coupling constant metamorphosis, also known
as the generalized Stäckel transform, is extended to general (not
necessarily Hamiltonian) dynamical systems,
