"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.

Building on previous preliminary results on the valuative tree at infinity (e.g., classification of valuations), I will describe the proof of Medvedev-Scanlon-Zhang conjecture for polynomial endomorphisms of the affine plane given by Junyi Xie in 2017.
