We introduce a novel data-driven approach to discover and decode features in the neural code coming from large population neural recordings with minimal assumptions, using cohomological learning. We apply our approach to neural recordings of mice moving freely in a box, where we find a circular feature. We then observe that the decoded value corresponds ...

Climate models have been the focus of much attention in the past three decades; indeed, they have been instrumental in highlighting the causes and consequences of anthropogenic climate change, and their results have largely contributed to climate policy and, in particular, the 2015 Paris Climate Accord. In this talk, we shall briefly outline the underlying ... Read more about "Climate models: their functioning, projections, and uncertainties"

(joint with Lei Zhang) I will discuss our recent proof on nonvanishing of terminal threefolds in characteristic p>5. The strategy is built on the original work of Miyaoka, but of course we have to deal with new phenomena in positive characteristics. Fortunately, all these ingredients, including the necessary Simpson correspondence type results, are developed recently. Read more about "Nonvanishing of threefolds in positive characteristics"

Polish topological groups comprise all locally compact second countable groups, but also most interesting topological transformation groups such as homeomorphism and diffeomorphism groups of compact manifolds, isometry groups of separable complete metric spaces, and automorphism groups of countable model theoretical structures. While all of these classes had been intensively studied separately, there has recently been ... Read more about "Structure and dynamics of Polish groups conference"

The topic of this workshop will be geometric group theory in a larger context. As is well known, there are close links between geometric group theory of finitely generated or locally compact groups and geometric non-linear functional analysis, i.e., the non-linear geometry of Banach spaces. While this has for a long time been seen as ... Read more about "Large scale geometry of Polish groups workshop"

The success of the probability theory in mathematics and theoretical physics is due not so much to its measure theoretic foundation but because it exploits and enhances symmetries of the structures it applies to. We shall describe in this lecture two alternative approaches to the concept of probability, where the first one is motivated by ...

Exceptional sets play an important role in numerous branches of mathematics, for instance in measure theory, topology, harmonic and complex analysis, Banach space theory, algebraic geometry, combinatorics, probability and ergodic theory, set theory and descriptive set theory, just to mention a few. Exceptional sets describe notions of smallness from various points of view, some notable ... Read more about "Ideals and exceptional sets in Polish spaces"

This is the last conference of the semester and will be of a more general nature than the earlier more specialized conferences and workshops of the program. It will cover broad aspects of descriptive set theory and its connections with other areas of mathematics. Read more about "Descriptive set theory conference"
