A scale-dependent effective action for gravity is introduced and an exact nonperturbative
evolution equation is derived which governs its renormalization group flow. It is invariant …

We discuss structural aspects of the functional renormalisation group. Flows for a general
class of correlation functions are derived, and it is shown how symmetry relations of the …

We discuss the exact renormalization group or flow equation for the effective action and its
decomposition into one particle irreducible N point functions. With the help of a truncated …

Quantum field theory has been a great success for physics, but it is difficult for
mathematicians to learn because it is mathematically incomplete. Folland, who is a …

Flow equations describe the evolution of the effective action Γk in the process of varying an
infrared cutoff k. The presence of the infrared cutoff explicitly breaks gauge and hence BRS …

Wilson's exact renormalization group equations are derived and integrated for the relevant
part of the pure Yang-Mills action. We discuss in detail how modified Slavnov-Taylor …

We study the fixed-point structure of the Higgs–Yukawa model, with its scalar being non-
minimally coupled to the asymptotically safe gravity, using the functional renormalization …

We describe scalar quantum electrodynamics by a gauge-invariant effective average action
Γ k. This is obtained by integrating out the quantum fluctuations with “momenta” larger than k …
