In the past 15 years, a new method of linearization of algebraic varieties was developed. The method, called tropicalization, associates to algebra-geometric objects over a valued field certain piecewise linear objects satisfying some harmonicity conditions. In my talk, I will…

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…
