Conferences attended
A running list of mathematics lectures, conferences, and workshops I've attended. Most have been at Parimaths (ENS Ulm, advanced group) — Saturday afternoon sessions, run by ENS students, doctoral candidates, and researchers. Original talk titles were in French; I've translated them below.
Conferences & competitions
Après-midi mathématique - ENS Paris
I took part in a mathematics competition at the École Normale Supérieure (ENS) in Paris, covering geometry, graph theory, and number theory. It was followed by lectures from Igor Kortchemski, Director of Research at the CNRS in Mathematics, and Ilia Itenberg, researcher and co-author of Mathematical Circles: The Russian Experience — on Kolmogorov's modern probability, graphs, and invariants.

If you're organising something I'd plausibly enjoy — differential geometry, mathematical physics, foundational logic, or anything math-philosophical — please write.
