Immersions of punctured 4-manifolds: with applications to Quantum Cellular Automata
Michael Freedman, Daniel Kasprowski, Matthias Kreck +2
Motivated by applications to pulling back quantum cellular automata from one manifold to another, we study the existence of immersions between certain smooth 4-manifolds. We show t…
Back to the roots: A discrete Kermack-McKendrick model adapted to Covid-19
Matthias Kreck, Erhard Scholz
A widely used tool for analysing the Covid-19 pandemic is the standard SIR model. It seems often to be used as a black box, not taking into account that this model was derived as a…
Studying the course of Covid-19 by a recursive delay approach
Matthias Kreck, Erhard Scholz
In an earlier paper we proposed a recursive model for epidemics; in the present paper we generalize this model to include the asymptomatic or unrecorded symptomatic people, which w…
Mapping class group of manifolds which look like -dimensional complete intersections
Matthias Kreck, Yang Su
In this paper we compute the mapping class group of closed simply-connected 6-manifolds which look like complete intersections, i.~e.~ and $…
Proposal of a recursive compartment model of epidemics and applications to the Covid-19 pandemic
Matthias Kreck, Erhard Scholz
This is work in progress. We make it accessible hoping that people might find the idea useful. We propose a discrete, recursive 5-compartment model for the spread of epidemics, whi…
Finiteness and infiniteness results for Torelli groups of (hyper-)Kähler manifolds
Matthias Kreck, Yang Su
The Torelli group of a closed smooth manifold is the subgroup of the mapping class group consisting of elements which act trivially on…
