## Horocycle flows on Abelian covers of hyperbolic surfaces – Davide Ravotti (Universität Wien)

The horocycle flow on the unit tangent bundle of a surface of constant negative curvature is the unit speed translation…

## Accelerate Sampling Using Birth-Death Dynamics – Lihan Wang (Carnegie Mellon University, Max Planck Institute Leipzig)

In this talk, I will discuss the birth-death dynamics for sampling multimodal probability distributions, which is the spherical Hellinger gradient…

## Matrix Whittaker processes – Elia Bisi (TU Wien)

Our journey starts from interacting random walks with push-and-block dynamics. We then consider their positive temperature analogues, touching upon polymer…

## Convergence rates and CLT for stochastic inviscid Leray-model with transport noise – Dejun Luo (Chinese Academy of Science)

Seminario SPASS: Dejun Luo…

## Nikodym-type spherical maximal functions – Alan Chang (Princeton University)

We study $L^p$ bounds on Nikodym maximal functions associated to spheres. In contrast to the spherical maximal functions studied by Stein and Bourgain, our maximal functions are uncentered: for each point in  $\mathbb R^n$, we take the supremum over…

## Lafforgue variety and $p$-adic representations – Kostas I. Psaromiligkos (University of Chicago)

We will construct the Lafforgue variety, a parametrizing space for the smooth irreducible representations of a $p$-adic reductive group $G(F)$. Our main tools will be Hecke algebras and a noncommutative version of the Hilbert scheme. The Lafforgue…

## The primitive equations with transport noise – Antonio Agresti (IST Austria)

The primitive equations are one of the fundamental models for geophysical flows used to describe oceanic and atmospheric dynamics. In…

## Turbulence Enhancement in Kinetic Coagulation Equations – Andrea Papini (Scuola Normale Superiore Pisa)

A Smoluchowski type model of coagulation in a turbulent fluid is given, heuristically expressed by means of a stochastic model…

## Central Sets and infinite monochromatic exponential patterns – Mariaclara Ragosta (Università di Pisa)

Schur’s Theorem (1916) states that for every finite coloring of $\mathbb N$ there exists a monochromatic triple $a, b, a+b$. Several decades passed before Folkman and Sanders extended this statement from two integers $a, b$ to arbitrarily long…

## Robust numerical integrators for dynamical low-rank approximation – Gianluca Ceruti (École Polytechnique Fédérale de Lausanne)

The discretization of time-dependent high-dimensional PDEs suffers from an undesired effect, the so-called curse of dimensionality: The amount of data to be stored and treated grows exponentially and exceeds standard capacity of common computational…
