Description

This lecture explores the derivation of simply laced Dynkin diagrams from the geometric properties of Du Val singularities in C^2/Gamma, where Gamma is a finite subgroup of SU(2). The slides cover topics such as the definition of singular points, resolution of singularities, blow-up of C^2, and the relationship between Du Val singularities and Dynkin graphs.
