Description

After a brief review of the main structural properties of the bi-metric implementation of Background Independence, some recent results obtained by means of bi-metric truncations of the effective average action will be discussed. The focus of the talk is on the possible existence of a "C-theorem" in 4 dimensional QEG, some of the pressing positivity issues in QEG, and, more technically, on new reliability tests for truncations which can be applied to any theory.
