Networks and Spacetime

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).

Abstract:

There 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.
