Previous Talks

December 11, 2024 › Esmée Theewis › Large deviations for stochastic evolution equations

This talk is about a new large deviation result for solutions to quasilinear SPDEs with small Gaussian noise. Read More ›

November 27, 2024 › Marilyn Korfhage › Percolation in the Poisson Boolean model

In her talk, Marilyn presents recent results on the Poisson Boolean model with convex grains. In particular, she presents conditions to distinguish whether the union of all grains cover the whole space, contains an unbouded connected component without covering the whole space, or decomposes in finite components only.

October 30, 2024 › Dennis Chemnitz › Dennis Chemnitz: Dynamical Properties of SDEs with Shear

In this talk, Dennis presents recent results on dynamical properties of SDEs with shear. Read More ›

September 25, 2024 › Martina Favero › Martina Favero: Stochastic processes in population genetics under strong selection

In this talk, Martina presents recent results on approximations of Wright--Fisher diffusions in the strong selection regime. Read More ›

August 28, 2024 › Ben Robinson › Bicausal optimal transport for SDEs with irregular coefficients

In this talk, Ben will present a method for comparing solutions of different SDEs, bringing together ideas from optimal transport, stochastic analysis, and numerical methods for SDEs with irregular coefficients. Read More ›

July 31, 2024 › Martijn Gösgens › The Projection Method: a Geometric Framework for Community Detection

In this talk Martijn presents the projection methods for community detection. Read More ›

June 26, 2024 › Lucas Roberto de Lima › First-passage percolation on random geometric graphs: Asymptotic shape and further results

This presentation delves into the first-passage percolation model, employing independent and identically distributed random variables on the infinite connected component of a random geometric graph. Read More ›

May 29, 2024 › Diala Hawat › Repelled point processes with application to numerical integration

In this talk, Diala will introduce a repulsion operator for Poisson Point Processes, which reduces clustering within configurations. This reduces the variance for the corresponding Monte Carlo estimator of integrals. Read More ›

April 24, 2024 › Alejandro Hernandez Wences › Lamperti Transforms of Self-Similar Measure-Valued Processes and Simple Coalescents

In this presentation, Alejandro will share his collaborative work with Arno Siri-Jégousse in which they derived a Lamperti transform for self-similar processes that take values in normed vector spaces. Read More ›

March 27, 2024 › Andjela Sarkovic › Cutoff for random walk on random graphs with a community structure

Andjela will discuss the random walk on a variant of the configuration with a community structure. She will prove results on whether this walk displays a cut-off phenomenon. This is a joint work with Perla Sousi and Jonathan Hermon. Read More ›

February 28, 2024 › Jonas Köppl › Dynamical Gibbs variational principles and applications

Jonas will be speaking about the long-time behaviour of interacting particle systems, that admit a Gibbs measure as stationary distribution. The aim of the talk is to derive that for translation-invariant systems also all possible limit points of the associated measure-valued dynamics are of Gibbs form. Read More ›

January 31, 2024 › Jiaming Chen › New stochastic Fubini theorem of measure-valued processes via stochastic integration

Jiaming will introduce a new equivalent of Fubini's Theorem for functions that are integrated with respect to a stochastic kernel from the predictable sigma - field to Z. Based on joint work with Tahir Choulli and Martin Schweizer. Read More ›

December 13, 2023 › Zsuzsa Baran › Phase transition for cutoff on graphs with an added weighted random matching

Zsuzsa will consider a range of graphs and then add an amount of randomness that can be characterised by a single parameter. She will then discuss, given this parameter, the cutoff phenomenon for a wide range of base graphs. Read More ›

November 29, 2023 › Luis Mario Chaparro Jáquez › A numerical scheme for SDEs with distributional drift

Luis will find the theoretical rate of convergence for the Euler-Maruyama method for SDEs with distributional drift. He will also implement a numerical scheme to compare his results. Read More ›

September 27, 2023 › Félix Foutel-Rodier › A spinal approach for the convergence of branching processes to the Brownian CRT

August 30, 2023 › Tara Trauthwein › Gaussian Approximation of Poisson Functionals via Malliavin-Stein Method

In this talk, Tara will explain how to find quantitative central limit theorems for functionals of a Poisson measure. An illustrative example using an on-line nearest neighbour graph will also be given. Read More ›

July 26, 2023 › Steffen Betsch › Pair interaction point processes

Steffen will discuss Point Processes with pair interactions, giving a rigorous definition of pair interaction process and providing guarantees of their existence. In the case of a repulsive interaction Steffen will prove that that this process is also unique. Read More ›

June 28, 2023 › Noah Halberstam › Infinite trees in the arboreal gas

The arboreal gas, alternatively known as the edge weighted unrooted spanning forest model, is equivalent to Bernoulli percolation conditioned to be acyclic.Using probabilistic techniques, Noah will show that in low dimensions d=3,4 the infinite tree is unique, and give strong heuristic evidence that the number of infinite trees is in fact infinite in higher dimensions.
