Invited talks

1. Understanding the complexity of frequency and phase angle fluctuations in power grids

   • Dynamics Days Europe, Lisbon, PT (2026) v2
   • 3rd British NetSci Symposium, King's College, London, UK (2026) v1 short
   • Workshop “Statistical Physics Methods for Sustainable Energy Systems”, Stellenbosch, ZA (2026) v1 long
   • Seminar at the University of the Free State, Bloemfontein, ZA (2026) v1 long
   Abstract Slides v2 Slides v1 long Slides v1 short Useful material Note

   The first versions of this presentation (v1 long and v1 short) contained a mistake. They reported the shares of electricity generation by source for Africa as a whole in 2023, based on data from the International Energy Agency. The corresponding figures for South Africa in 2023 are, of course, different and are reported here. The relevant figure has been corrected in the second version of the presentation (v2).

2. Message-passing on hypergraphs: detectability, phase transitions and higher-order information
   Complex Systems Seminar, Queen Mary University of London, London, UK (2025)
   Abstract Slides Video Note

   Slide number four contains a mistake that I also reiterated verbally during the presentation. I realized my mistake after reading this work. In the talk, I was not sufficiently explicit about what I meant when stating that “hypergraphs and graphs are different objects”. To clarify: I agree that every hypergraph admits an equivalent bipartite graph representation. Indeed, this equivalence is the modeling and algorithmic foundation of our paper. My intended point was different and simpler. Specifically, a hypergraph generally induces a factor graph that differs from the hypergraph's clique expansion.
