What is Koopman-von Neumann classical mechanics?

Koopman-von Neumann classical mechanics is a formulation of classical mechanics using a Hilbert space of complex, square-integrable functions. This operatorial framework shares structural similarities with quantum mechanics. It was developed by mathematicians Bernard Koopman and John von Neumann.

What we know

• Koopman-von Neumann theory describes classical mechanics as an operatorial theory similar to quantum mechanics. [1, 2]
• The framework is based on a Hilbert space of complex, square-integrable functions that represent classical observables on phase spaces. [1, 2]
• The theory was developed by Bernard Koopman and John von Neumann. [2, 5]
• It is mathematically related to the method of classical wavefunctions introduced by Mario Schönberg and others. [2] · medium confidence
