Generalized Dirac bracket and the role of the Poincaré symmetry in the program of canonical quantization of fields 1
arXiv:1010.5797
Abstract
An elementary presentation of the methods for the canonical quantization of constraint systems with Fermi variables is given. The emphasis is on the subtleties of the construction of an appropriate classical bracket that could be consistently replaced by commutators or anti--commutators of operators, as required by canonical quantization procedure for bosonic and fermionic degrees of freedom respectively. I present a consequent canonical quantization of the Dirac field, in which the role of Poincaré invariance is made marginal. This simple example provides an introduction to the Poincaré--free quantization of spinor electrodynamics in the second part of the paper.
