Colloquium: Tuesday, January 1, 2019. Speaker: Karim Adiprasito (Hebrew University). Title: “From Hall’s marriage theorem to algebraic geometry (and back to combinatorics)”.

We discuss how something remarkably similar to Hall’s marriage theorem appears naturally in context of a conjecture of Grothendieck in algebraic geometry, and how this is useful to prove some long-standing problems in discrete geometry. For instance, I will prove…
