Lots of good stuff happening in math blogging!
- Matt Baker is blogging! Lately: an appreciation of Robert Coleman, and Riemann-Roch for graphs.
- Frank Calegari is blogging! Actually he’s been blogging for a while but there’s tons of good stuff on here lately. Two recent posts that tie in closely with my own interests: The congruence subgroup property for thin groups, and The thick diagonal, in which Frank’s student Vlad Serban solves a puzzle I asked about, and much more besides. Also, Cheeseboard still wins.
- Adriana Salerno is blogging! Mostly about the profession and specifically the situation of young researchers in math. I like this post about collaborator visits because my old friend Leila Schneps, who taught me about the fundamental group, guest-stars in it!
- And just so it’s not all number theorists: Afonso Bandeira is blogging! I don’t even know this guy, but he’s writing tons of interesting stuff about problems in what I like to call “applied pure math,” questions about geometry of large sets and classification and convex relaxation and embeddings of metric spaces and etc. and etc.
