His algorithm gives a non-commutative, but associative, product (a so-called \"star-product\") between smooth phase space functions parameterized by Planck's constant $\\hbar$, which is treated as a deformation parameter. In the limit as $\\hbar$ goes to zero, the star product commutator goes to $\\hbar$ times the Poisson bracket, so in this sense his method provides a quantization of the algebra of classical observables. In this work, we develop a generalization of Fedosov's method which applies to the infinite-dimensional symplectic \"manifolds\" that occur in Lagrangian field theories. We show that the procedure remains mathematically well-defined, and we explain the relationship of this method to more standard perturbative quantization schemes in quantum field theory.", "revisions": [ { "version": "v1", "updated": "2016-03-31T15:07:51.000Z" } ], "analyses": { "keywords": [ "perturbative quantum field theory", "fedosov quantization", "smooth phase space functions", "lagrangian field theories", "finite-dimensional symplectic manifold" ], "tags": [ "dissertation" ], "note": { "typesetting": "TeX", "pages": 169, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160309626C", "inspire": 1437999 } } }
