#### Intersection Theory I - Rational Equivalence

###### Martino Fassina (Illinois Math)

Abstract: This is the first talk for our reading group on Intersection Theory. The material presented roughly corresponds to Chapter 1 of Fulton's book. I will introduce concepts such as cycles, rational equivalence, proper pushforwards and flat pullbacks. The focus will be on intuition and explicit examples.

#### To Be Announced

#### "Generic representations of abelian groups and extreme amenability" by J. Melleray and T. Tsankov (Part 3)

###### Dakota Ihli (UIUC)

Abstract: In this series of talks, we discuss the paper in the title [arXiv link]. In this final talk, we prove that the set of probability measure preserving automorphisms that topologically generate a copy of the group $L_0(\mathbb{T})$ is dense in $\mathrm{Aut}(\mu)$.
