SUMMARY
The discussion focuses on the significance of fixed points in renormalization group (RG) flow diagrams, particularly in quantum chromodynamics (QCD). It establishes that the choice between the unstable fixed point and the stable fixed point depends on the specific physical question being addressed. For high-energy scattering processes, calculations are performed near the ultraviolet (UV) fixed point, while for low-energy hadron spectrum analysis, the infrared (IR) fixed point is utilized through Monte Carlo simulations in lattice gauge theory.
