Title: Du Val singularities

Speaker: Inés García-Redondo

Abstract: In this talk, I will introduce Du Val singularities, a well-known type of isolated singularities of the complex plane that can be fully classified in correspondence with the simply laced Dynkin diagrams of types A, D and E (A-D-E classification). To obtain such classification one must study their resolutions i.e., take successive blow-ups of the singularity until arriving to a smooth variety. The idea for the talk is to cover how this is done through several examples and to later study some of the nice properties these singularities enjoy.

Some snacks will be provided before and after the talk.

This talk will be broadcasted via Zoom. Subscribe to the mailing list or contact organisers to get the Zoom details.

Junior Geometry Seminar
A weekly seminar run during term times on Fridays from 5:30–6:30pm. Most of the speakers and the audience are LSGNT students interested in geometry (algebraic, arithmetic, differential, metric, symplectic, you name it), though we plan to invite speakers from outside London in Terms 2 and 3 and everyone is welcome to join! 
The talks at the Seminar are meant to be accessible to all PhD students. We remind the speakers to assume as little prerequisites as possible and provide as much background as needed. We also encourage participants to ask questions whenever they feel like it — if you are confused, then chances are you are not alone, but everyone is too shy to ask.
