1 The Renormalisation Group and some Applications
1.1 The lectures of David Brydges
at the 2013 School on Mathematical Statistical Physics
http://www.math.ucla.edu/~biskup/Prague-school-2013/index.html
1.2 Abstract:
My goal is to explain the renormalisation group as a rigorous program to understand scaling limits. I will centre the lectures on recent work with Gordon Slade and Roland Bauerschmidt on log corrections in the susceptibility for the four dimensional Edwards model.
