Leo Herr (Leiden) - The Rhizomic Topology
What is a sheaf on a log scheme X? If we take the ordinary etale topology, we ignore the log structure. Taking the log ├ętale topology, even the structure "sheaf" O_X is not a sheaf! The same goes for M_X, \overline M_X. We introduce a new "rhizomic" topology on log schemes coarser than the log etale topology. Will this be enough?

Prof.dr. Joo Ho Choi (Korea Aerospace University) - Bayesian methods for uncertainty quantification

Abstract:Bayesian Methods for Uncertainty Quantification

This presentation discusses Bayesian theory andits applications in the field of reliability engineering. It addresses thebasic theory, philosophy, and simulation techniques to compute the posteriordistribution such as Markov Chain Monte Carlo and Particle Filtering methods.Application examples are the life prediction of Lithium-ion batteries, bladesin turbine engine, computer model calibration with uncertainty using real data,and crack growth prediction of aircraft structures.

Applied Mathematics Seminar -- Yves van Gennip (TUDelft) -- Some of the many faces of graph-based MBO


In 1992 Merriman, Bence, and Osher introduced a threshold dynamics scheme (later named the MBO scheme) for the approximation of flow by mean curvature. This scheme has proven to be very versatile and in the last decade its graph-based variants have found usage in many applications. In this talk we will take a look at some of those applications, such as graph clustering, maximum cut computations, signed graph clustering, and modularity optimisation. We will also discuss the relationship between graph-based MBO and the graph-based Allen--Cahn equation.

Title: Modeling the impact of Corona measures

AbstractIn this talk, I will discuss a model we have developed for the ministry of Health, Welfare and Sports to estimate the impact of Corona ticket measures (QR-code) on the spread of SARS-CoV-2 in the Netherlands. I will discuss how the underlying assumptions lead to the model formulation and I will briefly discuss some results.
