In the passage from classical mechanics to quantum mechanics, smooth
functions on symplectic manifolds (more generally, Poisson
manifolds) are replaced by operators on a Hilbert space and the Poisson
bracket of smooth functions is replaced by the commutator of the operators.
When one thinks of classical mechanics as a limit of quantum mechanics,
Poisson brackets become limits of commutators.
The formal algebraic approach to such a process is called formal deformation quantization. Its existence for every symplectic manifold was proven first by De Wilde and Lecomte, while the general case of Poisson manifolds was proven by Kontsevich.
A stricter approach to such a process is strict (deformation) quantization,
which is based on continuous fields of C*algebras (hence
everything is really operators on Hilbert spaces, compared to the formal
algebraic approach). However, the existence of strict quantization was
known only for special cases.
In this talk, I will give a construction of (nonHermitian) strict
quantization for every almost Poisson manifold.
