It does, however, contain all information concerning the system it describes, in accordance to the fundamental postulates of quantum mechanics [19]. From this a number of obser ...

Renormalization Group Flows for Quantum Gravity

In the modern (Wilsonian) point of view, the renormalization group (RG) is a flow of the action in some theory space, and represents the way physics change ...
