The rhizomic topology and tropical abelian varieties

May 28 at 16:0017:00 CEST

Leo Herr (Universität Leiden)

Abstract:
The log etale topology is a natural analogue of the etale topology for log schemes. Unfortunately, very few things satisfy log etale descent — not even vector bundles or the structure sheaf. We introduce a new rhizomic topology that sits in between the usual and log etale topologies and show most things do satisfy rhizomic descent! As a case study, we look at tropical abelian varieties and give some exotic examples.
