DDC Junior Seminar: Model theory and non-Archimedean analytic spaces September 22, 2020 (09:00 AM PDT - 10:00 AM PDT)
Parent Program: Decidability, definability and computability in number theory: Part 1 - Virtual Semester MSRI: Online/Virtual
Speaker(s) Jinhe Ye (University of Notre Dame)
Description

To participate in this seminar, please register here: https://www.msri.org/seminars/25206

The seminar will feature research talks by the six postdoctoral scholars appointed to the Fall 2020 DDC program, along with talks by students and other pre-tenure researchers associated with this program.  Since seminar attendees will have disparate backgrounds, we plan that these talks will not be too advanced, nor will they assume substantial background knowledge.  Our postdocs include number theorists, model theorists, and computable structure theorists, and talks can be expected to span all of these areas.

Berkovich space has been an important object in the study of non-Archimedean geometry. More recently, Hrushovski and Loeser have introduced a model-theoretic analogue of this object $\hat{V}$ via model theory of algebraically closed valued fields.  They used it to study the homotopy type of Berkovich spaces. In this talk, we will give an introduction to this object and describe some of my works around it.
