Abstract:
In these lectures I will introduce and explore
properties of the Renormalisation
Group (RG) both in its discrete and continuous forms. Topics
to be discussed include
multi scale expansions, the RG, Gaussian fixed points,
Wick products from the RG point of view,
ultraviolet cutoff removal, flow equations and perturbative
flows, trivial and non-trivial fixed points, and critical field theories.
Time permitting, I will discuss a rigorous application. These lectures
are supposed to be elementary.
