Title: Chern classes and obstruction theory
Speaker: Brad Wilson
Abstract: I will continue Selim’s lecture, giving a different interpretation of the first Chern class in terms of sections. This idea extends to define the higher Chern classes, which measure the failure of a collection of generic sections to be linearly independent. We will finish by looking at the properties of the Chern classes and give some example calculations.
Some snacks will be provided before and after the talk.
