Title: A Guide to Normal Surface Singularities
Speaker: Prof. DongSeon Hwang (Ajou University)
Normal surface singularities 'link' surfaces to 3-folds by means of smoothings and to 3-manifolds through links. In this lecture, I will present the classical foundation of the theory of normal surface singularities developed by Mumford, Artin, and Laufer with an emphasis on topological aspects, and then talk about the singularities coming from the developments of MMP. If time permits, I will sketch the proof of the classification of (log) terminal/canonical surface singularities.
