Title: Resolution of singularities of algebraic or analytic varieties.
Time, day and date: 4:00:00 PM - 5:00:00 PM, Thursday, October 23
Venue: Ramanujan Hall
Abstract: First I will show how to resolve curve singularities (this must be well-known to many). Then discuss Jung-Hirzebruch argument to get the equation of a surface in three variables in a very simple form, and then resolve its singularities. This will complete the proof of resolution of singularitiies of surfaces. Next, I will discuss some easy but useful results about resolution type results (resolution of indeterminacies, principalization, general notion of resolution of singularities, and their relations to each other).
