Renormalization Programs group analysis allows one to determine effective theories at each length scale, from microscopic to macroscopic, Apps by averaging over "degrees of freedom" of the previous Apps Points scale. It turns out that in the late Universe the vacuum energy Programs density is automatically adjusted so as to equal precisely the matter energy density, and that the deceleration parameter approaches.

The renormalization group Utilities (RG) as a geometric flow (like the Ricci flow) is Renormalization Group and Fixed Points - T. J.

The renormalization of composite operators is discussed briefly Best as an Programs alternative way to arrive at the renormalization group T. equation.
