Exotic Deformation Quantization

چکیده
Let A be one of the following commutative associative algebras: the algebra of all smooth functions on the plane: A = C(R), or the algebra of polynomials A = C[p, q] over R or C. There exists a non-trivial formal associative deformation of A called the Moyal ⋆-product (or the standard ⋆-product). It is defined as an associative operation A → A[[h̄]] where h̄ is a formal variable. The explicit formula is:

The Correspondence between Geometric Quantization and Formal Deformation Quantization
Using the classification of formal deformation quantizations, and the formal, algebraic index theorem, I give a simple proof as to which formal deformation quantization (modulo isomorphism) is derived from a given geometric quantization.
متن کاملNonperturbative effects in deformation quantization
The Cattaneo-Felder path integral form of the perturbative Kontsevich deformation quantization formula is used to explicitly demonstrate the existence of nonperturbative corrections to näıve deformation quantization. The physical context of the formal problem of deformation quantization is the original one set out by Dirac [1] in making the substitution
متن کاملOn the Representation Theory of Deformation Quantization
In this contribution to the proceedings of the 68 Rencontre entre Physiciens Théoriciens et Mathématiciens on Deformation Quantization I shall report on some recent joint work with Henrique Bursztyn on the representation theory of ∗-algebras arising from deformation quantization as I presented this in my talk. 2000 Mathematics Subject Classification: 53D55
متن کاملAn operadic approach to deformation quantization of compatible Poisson brackets
An analogue of the Livernet–Loday operad for two compatible brackets, which is a flat deformation of the bi-Hamiltonian operad is constructed. The Livernet–Loday operad can be used to define ⋆-products and deformation quantization for Poisson structures. The constructed operad is used in the same way, introducing a definition of operadic deformation quantization of compatible Poisson structures...
متن کاملDeformation Quantization - a Brief Survey
Quantization is, most broadly, the process of forming a quantum mechanical system starting from a classical mechanical one. See (Be) for an early attempt to obtain a general definition of quantization. (AbM) also provides an introductory account of the subject. There are various methods of quantization; see (BW) for a general introduction to the geometry of quantization, and a specific geometri...
