Query: The Role of Commuting Operators in Quantum Superintegrable Systems   We discuss the role of commuting operators for quantum superintegrable
systems, showing how they are used to build eigenfunctions. These ideas are
illustrated in the context of resonant harmonic oscillators, the Krall-Sheffer
operators, with polynomial eigenfunctions, and the Calogero-Moser system with
additional harmonic potential. The construction is purely algebraic, avoiding
the use of separation of variables and differential equation theory.
