ORAL SPECIALTY EXAM

TITLE: Realizibility of Tropical Curves

SPEAKER: Gabriel Dusing, University of Tennessee

TIME: 1:25 PM-2:15 PM

ROOM: Ayres 112

Tropicalization takes an algebraic curve and returns a tropical variety. Given a one-dimensional balanced polyhedral complex, is there an algebraic curve whose tropicalization is the complex? In the paper by Birkmeyer and Gathmann, the authors devise an algorithm to completely answer this question in the case that the curve is embedded in a specified plane. In addition to discussing this paper, I will outline a generalization in which the curve is not contained in a plane.
