Networks and Spacetime
Academic presentations can be uploaded in their original slide format. Presentations are usually represented as slide decks. Videos of presentations can be uploaded as media.
These are slides from an invited talk at a Workshop on Stochastic Topology and Networks held at Queen Mary University of London, 2 February 2018 (organisers Dr. Ginestra Bianconi, and Prof. Michael Farber, both QMUL).
are many data sets where the nodes in the most obvious representation come with
a natural order so these are Directed Acyclic Graphs. This order can be
interpreted as an arrow of time suggesting that the most natural geometrical
setting are spacetimes with their non-Riemannian geometry. In this talk I discussed this
idea in terms of simple models and analysis of several citation networks.
