The theory of the running of couplings is known as the renormalization group.
The null coordinate corresponds to the running of the renormalization group.
The renormalization group provides a detailed and quantitative explanation of critical phenomena.
In other words the prize was for his constructive theory of the renormalization group.
In the language of the renormalization group, this theory is known as the Gaussian fixed point.
The theory of renormalization group is based on this paradigm.
This complication is taken into account by the renormalization group.
The origin of scaling functions can be seen from the renormalization group.
All this follows from the theory of the renormalization group.
It is also used in studies of turbulence, as well as the renormalization group.
