Ricardo Carmo Vaz will complete his lecture from last week. Then Madalena Lemos will continue. Below is her abstract:

I will start by briefly reviewing the operator algebra, conformal blocks and
bootstrap. Then we will start discussing minimal models, following mainly
Chapter 7 of Di Francesco. The fusion rules will be presented in a heuristic
fashion, as well as the truncation of the operator algebra. Then we will see
that for certain conditions (minimal models) there's a finite number of
conformal families and we'll address the unitarity of these theories. If
time allows we'll briefly present a couple of examples of minimal models.

Ricardo Carmo Vaz will give the first introductory lecture on 2d CFT.

Abstract:

I will try to make an introduction to 2d Conformal Field Theory,
following mainly Ginsparg's Les Houches lectures. After quickly going
over some of features and constraints imposed by conformal invariance,
some of them in general but most of them in the case d=2, I will
discuss primary fields and their correlation functions, Ward
Identities. Then we can move on to study the central charge, the
Virasoro algebra, descendant states, and finally the Kac determinant
and unitarity conditions.

try to cover most of the first 4 chapters)
