Quantum Dirac constraints, Ward identities and path integral in relativistic gauge
A. O. Barvinsky
Quantum Dirac constraints in generic constrained system are solved by directly calculating in the one-loop approximation the path integral with relativistic gauge fixing procedure.…

Solution of quantum Dirac constraints via path integral
A. O. Barvinsky
The semiclassical solution of quantum Dirac constraints in generic constrained system is obtained by directly calculating in the one-loop approximation the gauge field path integra…

Wheeler-DeWitt equation and Feynman diagrams
A. O. Barvinsky, C. Kiefer
We present a systematic expansion of all constraint equations in canonical quantum gravity up to the order of the inverse Planck mass squared. It is demonstrated that this method g…
