Title: " The rhizomic topology and tropical abelian varieties"
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.

Title: "Capturing Brain dynamics using Topological Data Analysis "
Abstract:
Characterizing intrinsic and extrinsic transitions in cortical activity can provide an understanding of cognition, e.g.,
how the ebbs and flows of cognition are anchored in the transitions of neural activity. Further, such anchoring could facilitate better models
for psychiatric disorders and provide novel avenues for cognitive enhancement. This talk explores how noninvasive neuroimaging, despite its inherent limitations,
can be leveraged to anchor cognitive performance and psychiatric nosology into rich spatiotemporal dynamics. We propose using tools from Topological Data Analysis (TDA),
especially Mapper, to tackle the inherent noise in noninvasive neuroimaging devices and for capturing and characterizing brain dynamics in healthy and patient populations.
This talk is part of the activity of the MIUR Excellence Department Projects MatMod@TOV.

Title: " The double semion model in infinite volume "
Speaker: Jacopo Bassi - Ben-Gurion University of the Negev, Be’er Sheva
Abstract:
Abstract:
Motivated by the problem of determining whether biexactness, the (AO)-property and von Neumann solidity are equivalent
properties for a discrete countable group, I will discuss few recent results regarding analytic properties of SL(3,Z),
related to hyperbolicity. I will focus on the role of measurable dynamics and proximality arguments in this context.
Partly based on joint works with F. Radulescu and T. Amrutam
