This week at Harvard’s CMSA there’s a program on Arithmetic Quantum Field Theory<\/a> that is starting up and will continue through March. There’s a series of introductory talks going on this week, by Minhyong Kim, Brian Williams, and David Ben-Zvi. I believe video and\/or notes of the talks will be made available.<\/p>\n

At the IHES and the Max Planck Institute, the Clausen-Scholze joint course on analytic stacks<\/a> has just ended. For an article (in German) about them and the topic of the course, see here<\/a>. What they’re working on provides some new very foundational ideas about spaces and geometry, in both the arithmetic and conventional real or complex geometry contexts. Many of the course lectures are pretty technical, but I recommend watching the last lecture<\/a>, where Scholze explains what they hope can be done with these new foundations.<\/p>\n

Of the applications, the one that interests me most is the one that was a motivation for Scholze to develop these ideas, the question of how to extend his work with Fargues on local Langlands as geometric Langlands to the case of real Lie groups. He’ll be giving a series of talks about this at the IAS<\/a> next month.<\/p>\n

Something to look forward to in the future is seeing the new Clausen-Scholze ideas about geometry and arithmetic showing up in the sort of relations between QFT, arithmetic and geometry being discussed at the CMSA.<\/p>\n","protected":false},"excerpt":{"rendered":"
