New proposal for Lorentzian renormalisation group flow equations on curved spacetimes
Appears in collection : 2024 - PC1 - WS - Curved spacetimes, field theory and beyond
In this talk I will present recent results obtained in collaboration with d’Angelo, Drago and Pinamonti. We proposed a new formulation of renormalisation group flow equations that work on arbitrary globally hyperbolic spacetimes and for any chosen Hadamard state. The examples treated so far include the scalar field, Yang-Mills theories and gravity.
