Non-perturbative — In mathematics and physics, a non perturbative function or process is one that cannot be accurately described by perturbation theory. An example is the function . The function e 1/x². The Taylor series is 0, but the function is not. The Taylor… … Wikipedia
Beta-function — In theoretical physics, specifically quantum field theory, a beta function β(g) encodes the dependence of a coupling parameter, g, on the energy scale, mu of a given physical process. It is defined by the relation:::eta(g) = mu,frac{partial… … Wikipedia
