I always learn a lot from reading the papers of Michel on reinforced processes and Markov chains. Highly recommended.

very exciting: some theoretical results on the implications of metric curvature assumptions for Markov chains, both confirming and refuting open conjectures! arxiv.org/abs/2309.06493 'Ollivier curvature, Isoperimetry, concentration, and Log-Sobolev inequality' - Florentin Münch

💡 INTERVIEW | In an interview for The Edge Singapore, ESSEC Business School Professor @PierreAlquier talks about the needs, and challenges, of adopting AI tools for non-IT staff. The safe use of AI is also a key element on which every company employee should be trained. bit.ly/3LGNeEq

[1/3]: What is a two-person Markov chain entropy game of a probabilist against Nature? What is the geometry of the Nash equilibria? Very proudly presenting a joint work with Geoffrey Wolfer: “Markov chain entropy games and the geometry of their Nash equilibria"

A tidal wave of new primary sources from the ancient world could very soon be on its way - enough to keep scholars busy for decades! The first words have being read from digitally ‘unrolled’ carbonised scrolls from a Roman library in Herculaneum! (Image: Nat Friedman)

The polynomial Freiman-Ruzsa conjecture has been solved! gilkalai.wordpress.com/2023/11/13/mar…
