2D gravity in weak coupling limit
arXiv:gr-qc/0404087 · doi:10.1016/j.physletb.2004.05.045
Abstract
2D quantum gravity in infinitely large invariant volume is considered. In weak coupling limit the dynamics is reduced to quantum mechanics of a single degree of freedom. The correspondent two - point Green function is calculated explicitly in Gaussian approximation.
