Spacetime reconstruction and measured Lorentz-Gromov-Hausdorff convergence

Mathias Braun
(École Polytechnique Fédérale de Lausanne (EPFL))
Abstract

We present Gromov's celebrated reconstruction theorem in Lorentzian geometry and show two applications. First, we introduce several notions of convergence of (isomorphism classes of) normalized bounded Lorentzian metric measure spaces, for which we describe several fundamental properties. Second, we state a version within the spacetime reconstruction problem from quantum gravity. Partly in collaboration with Clemens Sämann (University of Vienna).

Oxford Temporary Congestion Charge

As you might already know, the Oxford Temporary Congestion Charge has been approved and is planned to come into effect on Wednesday, 29 October 2025. There are various permits available.

Maybe one of you can create the shortest route to avoid all the charge zones. Or the shortest way to drive them all...
