Introduction to the Renormalisation Group

Presented by: 
Pronob Mitter
Friday 16th November 2018 - 11:00 to 12:30
INI Seminar Room 2
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.
