Lewis Napper was in Germany the past two weeks. He was an invited participant and speaker at the “Interdisciplinary junior scientist workshop on Mathematical General Relativity“. It was held from 26 February to 10 March in Haus Saron in Wildberg Germany, organised by the Institute for Mathematics at the University of Potsdam. Lewis spoke on day two on “Globalization of timelike curvature bounds in Lorentzian length spaces“. A link to the workshop website is available (link here) and the image below shows that header of the workshop webpage.
