Callan-symanzik β( g) function in different topological sectors
Abstract
Using the formalism developed by Amati and the present author for constructing a perturbation theory around an instanton in gauge theories, it is proved that the Callan-Symanzik β( g) function is the same as in the perturbation theory developed around zero.
