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

@highergeometer looks like I'm Massey's Basic Algebraic Topology, and, based only on color scheme and not the quiz, Pedro 🐈 is upside-down Hartshorne. #cats #CatsOfMastodon #Caturday

Pedro the #Math Cat and his white paws also match some other upside-down GTMs

Pedro the #Math Cat 🐈 is cute and innocent and definitely not the leopard who proved Your theorem. #cats #Caturday #CatsOfMastodon

Pedro is adorable but also looking a little judgey.

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...

Remember this classic example of a bounded multivariable function \\[f(x,y)=\frac{xy}{x^2+y^2}\\] where the partial derivatives exist but \\(f\\) is discontinuous because it has different limits in different directions? I used the free plotting app on […] [Original post on mathstodon.xyz]
