ADE Dynkin Diagrams and du Val Singularities

Friday, October 22, 2021, 5:00pm
Ungar Building Room 402


Abstract:

Dynkin diagrams are certain finite graphs (we saw them in previous lectures of Hsin Chieh). Developed originally for use in the representation theory of Lie groups and algebras, they surprisingly occur in many other areas of mathematics. In this talk, we will see how they emerge in the study of singularities of holomorphic functions. Du Val singularities, classified by Dynkin diagrams, may serve as a gentle introduction to the vast subject of singularity theory.
