"Hyperplane Arrangements and Compactifying the Milnor Fiber"

Milnor fibers are invariants that arise in the study of hypersurface singularities. A major open conjecture predicts that for hyperplane arrangements, the Betti numbers of the Milnor fiber depend only on the combinatorics of the arrangement. I will discuss how tropical geometry can be used to study related invariants, the virtual Hodge numbers of a hyperplane arrangement's Milnor fiber. This talk is based on joint work with Max Kutler.

"Preparing for polynomial dynamics of the affine plane"

We will begin applying our knowledge of the valuative tree to the case of polynomial dynamics of the affine plane. Our goal is to begin understanding when a dominant polynomial morphism of the affine plane has a zariski dense orbit.
