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.
Series This talk is part of the Isaac Newton Institute Seminar Series series.
