Functional Renormalization Group Flows on Friedman–Lemaître–Robertson–Walker backgrounds

Research output: Contribution to journalJournal articleResearchpeer-review

We revisit the construction of the gravitational functional renormalization group equation tailored to the Arnowitt–Deser–Misner formulation emphasizing its connection to the covariant formulation. The results obtained from projecting the renormalization group flow onto the Einstein–Hilbert action are reviewed in detail and we provide a novel example illustrating how the formalism may be connected to the causal dynamical triangulations approach to quantum gravity.
