Elementary Model of Constraint Quantization with an Anomaly
arXiv:gr-qc/0502045 · doi:10.1103/PhysRevD.71.085014
Abstract
Quantum gravity is made more difficult in part by its constraint structure. The constraints are classically first-class; however, upon quantization they become partially second-class. To study such behavior, we focus on a simple problem with finitely many degrees of freedom and demonstrate how the projection operator formalism for dealing with quantum constraints is well suited to this type of example.
