e/Infrared fixed point

Information
has gloss	eng: In physics, an infrared fixed point is a set of coupling constants, or other parameters that evolve from initial values at very high energies (short distance), to fixed stable values, usually predictable, at low energies (large distance). This usually involves the use of the renormalization group, a mathematical apparatus for theoretically evolving physical systems from one scale to another.
