Deformation Quantization  

In General > s.a. geometric quantization; quantum group; schrödinger equation [generalizations]; Star Product.
* Idea: An approach to quantization in which the classical algebra of observables for a physical systems is replaced by a deformed algebra, with multiplication replaced by a (non-commutative but associative) star product; The best known example is the Moyal star product.

* Idea: A deformation of the Heisenberg algebra (commutators) leads to modified uncertainty relations, which could correspond to the existence of a minimal length.

* Normal star product: Can use the non-commutative star product f *g := exp{\(\hbar\)∂aa*} f(a) g(a*), where a and a* are holomorphic coordinates on phase space; Does not work for the simple harmonic oscillator because it gives En = \(\hbar\)ωn without the 1/2 (Moyal brackets are better in this sense), but may be desirable in quantum field theory.
* Fedosov formalism: A generalization of the Moyal star product for an arbitrary symplectic manifold, based on a symplectic torsion-free affine (Fedosov) connection.
