Bi-annual Algebraic and Tropical Meetings of
Brown and YaLE

November 29, 2018

The BATMOBYLE is a vehicle for bringing together the algebraic and tropical geometry groups of Brown and Yale for a biannual day of talks alternating between the two universities.

Real tropicalization and analytification of semialgebraic sets

Semialgebraic sets are those defined by polynomial inequalities over an algebraically closed field. In this talk I will discuss their tropicalization and analytification. We show that the real analytification is homeomorphic to the inverse limit of real tropicalizations, analogously to a result of Payne. We also show a real analogous of the fundamental theorem of tropical geometry. The talk will be accessible to graduate students with background on basic algebraic geometry. This is based on joint work with Philipp Jell and Claus Scheiderer.
