Covariance in models of loop quantum gravity: Spherical symmetry
Covariance in models of loop quantum gravity: Spherical symmetry
Spherically symmetric models of loop quantum gravity have been studied recently by different methods that aim to deal with structure functions in the usual constraint algebra of gravitational systems. As noticed by Gambini and Pullin, a linear redefinition of the constraints (with phase-space dependent coefficients) can be used to eliminate …
