Pierre says Happy New Year!
I'm really fascinated right now with how sufaces, foliations, Culler-Vogtmann outer space, tropical geometry, & physics all fit together. So we have a surfaces, tropical geometry, & physics working group. Today I talked about the CP coordinates.
I'm in Montreal :D. But I can guarantee that my mom has been updating me on the Mariners enough for everyone! She's very excited!
I have a new webpage with a research image carousel: www.catherinepfaff.com . Click on an image & see what happens!
I'm in Hawaii this week giving a minicourse! sites.google.com/hawaii.edu/s...
Something extraordinary for me about the IAS is the intergenerationality & inclusion of "wise elders." I will always treasure the special bond Pierre & I developed with the greatests of greats, Karen Uhlenbeck. Our many meals, math & life conversations, something very special...
Always wonderful to see a former student thriving & sharing that they'll be at your location! Howie Hong at IAS!
It's somehow not the most flattering video of me, but here I am talking about talking about simplicial complexes at the Institute: www.youtube.com/watch?v=nhcm...
I'm excited that I'll be spending 2 months at l'Institut des Hautes Γtudes Scientifiques in Orsay (right outside Paris) Spring 2026!
Reading a book from 1989 that refers to a book from 1985 as an up-to-date reference. Perhaps that wording doesn't quite stand the test of time...
Among last week's IAS shenanigans was trying to reenact an Oppenheimer scene with Professor Flores. I chose to asssume that in reality there was actually a dog present in that moment of history.
Last Groups & Dynamics Seminar talk of the year. It's been lovely, thank you to everyone for your time & generosity! youtu.be/Q9Y1AReegNg?...
There was a bit of a mix-up on the IAS end, but here now is Lee's excellent talk: www.youtube.com/watch?v=ZB-r...
PhD advisor Lee Mosher & his current student Sarasi Jayasekara visited me at IAS today for Lee's talk. Really wonderful talk & day!
@petraschwer.bsky.social I think that the real problem is that you're an expert on too many things :).
Oh, wait, it's on CAT(0) cube complexes!?! Very cool! And sorry I mixed up the topic :)
Btw, her colloquium talk at IAS can be found at youtu.be/z9lg-y19ajs?...
Pierre was attending her "What is...?" seminar talk. She also wrote a book on buildings.
Pierre enjoyed learning about buildings this week from Petra Schwer!
Great talk by Joseph Maher this week!

This beautiful mathematical story was a highlight of the week for sure! Thanks Rob Silversmith!
Really great visiting Yale earlier this week & chatting with Eduardo Reyes there!
Episode 2 today with her collaborator also. Very fun & exciting conversations!
Dr. Brandis Whitfield defended her thesis last week & spoke at IAS this week! www.youtube.com/watch?v=Rjtt...
Thomas Koberda's excellent talk here at the Institute for Advanced Study! www.youtube.com/watch?v=iKNj...
Maybe it makes my papers look expensive too? :)
Yep! I discovered that I have an easier time reading black on ivory than black on white & figured I'm likely not the only person like that. So I've started using it as much as possible, have overall tried shifting to a more eye-friendly palette over time...
I have one of those too! And I also often misread people's math tweats when my brain isn't in full focus mode :).
So much going on that I forgot to share that Chi Cheuk Tsang & I have a new preprint! Really fun project, where we give a "cubist" decomposition of the collection of axes for a fully irreducible & use it for the conjugacy problem. arxiv.org/abs/2503.16360
