Another talk that I moderated at #icm2026 - again my gracious introduction did not make it into the video, but around 35:58/40:17 I am barely audible, giving the speaker the 5-minute alert and asking him to read the blue line on the slides, which was pretty much illegible in the room but shows […]

Pedro the #Math Cat 🐈 had his vet appointment and was diagnosed with chonk. Considering that one of his main jobs is cuddling, I don't mind a bit of chonkitude, but the catdoctor says it's aggravating his asthma, so it's diet time for Pedro. #cats #CatsOfMastodon #Caturday

I've submitted my abstract for a talk at #JMM2027 in #Chicago - assuming it's accepted, I will be speaking about the inhomogeneous Cauchy-Riemann equation. I also signed up to judge some student posters. See you there?? #Riemann200 #MathConference #ComplexAnalysis :gauss:

Pedro is adorable but also looking a little judgey.

A #HistoryOfMath moment, for no particular reason... My usually taciturn PhD advisor once related an anecdote about his experience as a Chern student (so, 1970s) - he said Chern was of the opinion that there were infinitely many complex structures on \\(S^6\\) - but that they were just hard to find.

G. Segal (still) not at #icm2026 so his #ChernMedal lecture on The Abstract Structure of QFT was shown as a pre-recorded video, with a few remarks about Chern at the start. (The video may be on YouTube later, not the same as his award profile video)

Most of the video was him narrating slides like this. Some interesting remarks on real and complex structures on algebras...
