A co-publication of the AMS and Centre de Recherches Mathématiques

Superintegrable systems are integrable systems (classical and quantum) that
have more integrals of motion than degrees of freedom. Such systems have many
interesting properties. This proceedings volume grew out of the Workshop on
Superintegrability in Classical and Quantum Systems organized by the Centre de
Recherches Mathématiques in Montréal (Quebec). The meeting brought
together scientists working in the area of finite-dimensional integrable
systems to discuss new developments in this active field of interest.

Properties possessed by these systems are manifold. In classical mechanics,
they have stable periodic orbits (all finite orbits are periodic). In quantum
mechanics, all known superintegrable systems have been shown to be exactly
solvable. Their energy spectrum is degenerate and can be calculated
algebraically. The spectra of superintegrable systems may also have other
interesting properties, for example, the saturation of eigenfunction norm
bounds.

Articles in this volume cover several (overlapping) areas of research,
including:

– Standard superintegrable systems in classical and quantum mechanics.

– Superintegrable systems with higher-order or nonpolynomial integrals.

– New types of superintegrable systems in classical mechanics.

– Superintegrability, exact and quasi-exact solvability in standard and
PT-symmetric quantum mechanics.

– Quantum deformation, Nambu dynamics and algebraic perturbation theory of
superintegrable systems.

– Computer assisted classification of integrable equations.

The volume is suitable for graduate students and research mathematicians
interested in integrable systems.

Titles in this series are co-published with the Centre de Recherches Mathématiques.
