"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.

In this very kick-off talk, we will go through section 1.1. We aim to recall/learn some basic notions of manifolds with boundary and orientations, and Morse functions in the section. We also introduce the slightly nonstandard notion of in-boundary and out-boundary, which is particularly convenient for the treatment of cobordisms. Besides, we will take about the outline and the goals of this seminar.

"Approximating reals by rationals"
Andrej Vukovic, Department of Pure Mathematics, University of Waterloo
This week, we continue our study of topological quantum field theories by discussing Morse theory and introducing the notion of cobordism.
