Current state vector

• Preparing for the Caltech Mathathon - super excited to be a part of it!
• Back from the ASC School on Generalized Symmetries - Arnold Sommerfeld Center, LMU Munich, 5 - 9 October 2026 - school page ↗.
• New preprint with A. V. Kiselev: The counts of parity-odd vs even late-growing permutations in the group S2p−1 differ by (−1)p - arXiv:2610.35779. The ornament from it is now on the site.
