L’utilizzo degli ultrafiltri su $\mathbb N$ per descrivere le proprietà di ricorrenza in dinamica topologica è un tema di ricerca ben studiato (tra gli altri, da Bergelson, Blass, Hindman e Strauss). In particolare, lo spazio $\beta\mathbb N$ degli…

Parabolicity conjecture of F-isocrystals – Marco D’Addezio (Université de Paris)
In the last years the theory of crystalline cohomology and F-isocrystals had a great development. I will present a new result concerning the algebraic monodromy groups of F-isocrystals. I will start with a quick introduction on crystalline…

Coarse homology theories – Luigi Caputi (University of Aberdeen)
Coarse spaces, first introduced by J. Roe for studying index-type theorems, have recently found applications also in K-theory and assembly map conjectures. The main tool in such applications is given by coarse homology theories, homological…
Inviscid Limit for Stochastic Navier-Stokes Equations in 2D Domains with Boundary – Eliseo Luongo (Scuola Normale Superiore Pisa)
We prove some conditioned results for the inviscid limit of the stochastic Navier-Stokes equations with additive noise to the deterministic Euler equations, in a smooth 2 dimensional bounded domain in the case of no-slip boundary conditions. This…
Construction of a sequence of orthogonal rational functions – Raf Vandebril (Department of Computer Science, KU Leuven)
Orthogonal polynomials are an important tool to approximate functions. Orthogonal rational functions provide a powerful alternative if the function of interest is not well approximated by polynomials. Polynomials orthogonal with respect to certain…

Variation of stable birational type and bounds for complete intersections – Johannes Nicaise (KU Leuven and Imperial College London)
This talk is based on joint work with John Christian Ottem. I will explain a generalization of results by Shinder on variation of stable birational types in degenerating families, and how this can be used to extend Schreieder’s non-stable…
