MaPSS: Mathematical Postgraduate Seminar Series: Edwin Spark -- The McKay Correspondence: An introduction to ADE Classification

Dear All,

We are delighted to present the MaPSS Seminar topic of Monday 29/08; please see the
abstract below.

**This Semester the Seminar will always run on Monday, at 5:00pm in 535A**

Following the talk, there will be pizza on offer.

Speaker: Edwin Spark (Sydney University)

Title: The McKay Correspondence: An introduction to ADE Classification

Abstract: Dynkin diagrams (sometimes referred to as Coxeter-Dynkin diagrams) appear in
many independent classification theorems, particularly those diagrams of ADE type.  In
this talk we will characterise these simply laced diagrams, which can be thought of as
graphs, and then look at an example of an ADE classification: the McKay correspondence
that connects the classification of finite subgroups of SL(2) to the classification of
affine Dynkin diagrams.
