Title: Cohomological Intersection Theory II
Speaker: Timmy Feng
Abstract: This week's talk continues our exploration into cohomological intersection theory. A central theme of our discussion will be the definition of the virtual fundamental class for derived Artin stacks—a pivotal development that extends the applicability of the Graber-Pandharipande formula. Additionally, we will examine the invertibility of the Euler class within this novel context. And finally, we will provide a rough proof of Graber-Pandharipande formula.
