List of Figures

View Image Figure 1:
Schematic form of the linearized flow of the s- l, l ≥ 1, perturbations; t = -1 ln μ∕μ 2π 0, p ϱ = ρ.
View Image Figure 2:
Flow pattern in the gλ plane with a sharp mode cut-off. The arrows point in the direction of the coarse graining, i.e. of decreasing k. (From [181].)
View Image Figure 3:
Trajectory of the linearized flow equation obtained from the R2-truncation for − 1 ≥ t = ln(k0∕k) > − ∞. In the right panel we depict the eigendirections and the “box” to which the trajectory is confined. (From [132].)
View Image Figure 4:
g∗, λ ∗, and g∗λ∗ as functions of s for 1 ≤ s ≤ 5 (left panel) and ν∗ as a function of s for 1 ≤ s ≤ 30 (right panel), using the family of exponential shape functions (4.51View Equation). (From [132].)
View Image Figure 5:
θ′ = − Re ϑ1 and θ′′ = − Im ϑ1 (left panel) and θ3 = − ϑ3 (right panel) as functions of s, using the family of exponential shape functions (4.51View Equation).
View Image Figure 6:
Schematic view of the action flow in the vicinity of a (UV) fixed point. Shown is a typical flow line (black) and a renormalized trajectory (red) emanating from the fixed point. The arrows on the flow lines give the direction of the coarse graining, i.e. of decreasing l or increasing t.
