C*-algebras satisfying the UCT form an analytic set

Michał Szachniewicz
(University of Oxford)
Abstract

I will sketch a proof of the statement in the title and outline how it is related to Ehrenfeucht–Fraïssé games on C*-algebras. I will provide the relevant background on C*-algebras (and descriptive set theory) and explain how to construct a standard Borel category X that can play a role of their `moduli'. The theorem from the title is an application of the compactness theorem, for a suitable first-order theory whose models correspond to functors from X. If time permits, I will mention some related problems and connections with conceptual completeness for infinitary logic. This talk is based on several discussions with Ehud Hrushovski, Jennifer Pi, Mira Tartarotti, and Stuart White after a reading group on the paper "Games on AF-algebras" by Ben De Bondt, Andrea Vaccaro, Boban Velickovic and Alessandro Vignati.

Introduction to Arakelov theory

Michał Szachniewicz
(University of Oxford)
Abstract

I will talk about preliminaries in Arakelov geometry. Also, a historical overview will be provided. This talk will be the basis of a later talk about the theory of globally valued fields.

How about Roger Penrose and his obsessional walks? Or a mathematical joke about an errant dog? Or more from agony uncle Josh Bull as he tells us how to best stir your tea? All three and more feature in our latest short films which you can watch on YouTube. Roger's film and the link to them all are in the full article including Mie Gluckstad (image) on the pros and cons of random walks.
