Phys. Rev. D 71, 085014 (2005) [6 pages]Elementary model of constraint quantization with an anomalyReceived 10 February 2005; published 22 April 2005 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. © 2005 The American Physical Society URL:
