Title: Singularity formation in incompressible fluids. Abstract: I will discuss a recent example of singularity formation in the 3d Euler equation. This is based on work joint with Federico Pasqualotto.

Title: Bipartite Euler SystemsAbstract: I will give an example-based introduction to bipartite Euler Systems, starting with the construction in the case of Heegner points by Bertolini--Darmon from the early 2000's. I'll discuss the main obstacles in extending such methods to other settings, and survey some of the new constructions we have seen in the last […]

Title: Oscillatory integrals on manifolds and related Kakeya and Nikodym problems. Abstract: This talk is about oscillatory integrals on manifolds and their connections to Kakeya and Nikodym problems on manifolds. There are two types of manifolds that are particularly interesting: manifolds of constant sectional curvature and manifolds satisfying Sogge's chaotic curvature conditions. I will discuss these two […]
Title: Light condensed setsAbstract: This talk will introduce us to the light condensed setting, the new way of dealing with set-theoretic technicalities in the condensed setup. Particular emphasis will be on the changes, differences, and simplifications compared to the "old" approach, which we discussed last semester.
Title: A moduli-theoretic approach to heights on stacks.Abstract: A theory of heights of rational points on stacks was recently introduced by Ellenberg, Satriano and Zureick-Brown as a tool to unify and generalize various results and conjectures about counting problems over global fields. In this talk I will present a moduli theoretic approach to heights on stacks over […]
Title: Restricted Arithmetic Quantum Unique ErgodicityAbstract: The quantum unique ergodicity conjecture of Rudnick and Sarnak concerns the mass equidistribution in the large eigenvalue limit of Laplacian eigenfunctions on negatively curved manifolds. This conjecture has been resolved by Lindenstrauss when this manifold is the modular surface assuming these eigenfunctions are additionally Hecke eigenfunctions, namely Hecke-Maass cusp forms. I […]

Title: Arithmetic Quantum Field Theory? Abstract: Mathematical structures suggested by quantum field theory have revolutionised important areas of algebraic geometry, differential geometry, as well as topology in the last three decades. This talk will introduce a few of the recent ideas for applying structures inspired by physics to arithmetic geometry.
