The London Mathematical Society Women and Diversity in Mathematics committee has made their Diversity Days grant more flexible so that you can apply for an event that focusses on EDI more broadly. If you're thinking of doing a UK-based EDI maths event this academic year, apply! (by Oct 31) lms.ac.uk/grants/lms-inc…

We love to see this!! Congratulations to Chi Onwurah 💙 !

The cat is out of the bag. In 2025, I am joining Queen Mary Maths as a Professor of Pure Mathematics in their Centre for Combinatorics, Algebra, and Number Theory (CeCANT). I’m excited for this new part of my career. seresearch.qmul.ac.uk/ccant/

Today, I need a remake of the Ace of Base song that is now "I saw the sign (error)."

I just got sent in my overseas ballot. If you can then you should too.

🚨Cat is out of the bag.🚨 I am excited to join the People Diversity Advisory Panel for REF 2029 to try to make the framework as inclusive as the Powers That Be allow... #REF2029

I remember my real analysis class. It was a directed study. My professor handed baby Rudin to me and another student and said "Get to it." I was also doing a directed study for Hartshorne. College was wild.

Algebraic geometers. The next installment of GAeL is here. It's June 16-20 in Toulouse. I'm giving a mini-course loosely around topics in mirror symmetry as a 'senior speaker.' Send your PhD students! Applications are open below. sites.google.com/view/gaelxxxii…

Well....I hope my coauthor is ok with this excuse on why the file hasn't changed today.

Arxiv posting day. My first paper in math.NT without a math.AG crosspost comes out tomorrow.

New paper day.

Mark Gross (@cambridge_uni), Paul Hacking (UMass Amherst), Seán Keel (@utaustin) and Maxim Kontsevich (Institut des Hautes Études Scientifiques - IHES) will receive the 2025 AMS E.H. Moore Research Article Prize. They are honored for the paper “Canonical Bases for Cluster Algebras.” Full story on website.

First day of new job.

Can someone in the UK government (DSIT?) please put out the welcome mat for US scientists, especially those in public health, vaccines and mRNA research. Trump might not want them. We absolutely do.
