The solutions Γ Γ k of the FRGE interpolate between the bare (microscopic) action at k → → ∞ ∞ and the effective action Γ Γ [ Φ Φ ] = Γ Γ k = 0 [ Φ Φ , Φ Φ ¯ ¯ = Φ Φ ] at k → → 0 . They can be visualized as trajectories in the underlying theory space. Note that the FRGE itself is independent of the bare action. In the case of an asymptotically safe theory, the bare action is determined by the fixed point functional Γ Γ ∗ ∗ = Γ Γ k → → ∞ ∞ .
