Bi-annual Algebraic and Tropical Meetings of
Brown and YaLE
(BATMOBYLE)

Spring 2016 @ Yale
April 28, 2016


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.

Geometric invariants of non-archimedean semi-algebraic sets

Semi-algebraic sets over non-archimedean fields appear naturally in tropical and non-archimedean geometry. I will explain how one can use Hrushovski and Kazhdan's theory of motivic integration to attach geometric invariants to semi-algebraic sets, and how to compute these invariants by means of tropical techniques.

This talk is based on joint work with Sam Payne and Franziska Schroeter.
