Learning Seminar on BMS2 (Spring 2020)


Time: 2:30 pm - 4:00 pm on Fridays
Location: Mason Hall 2330

This semester Shubhodip Mondal and I are organizing a learning seminar on (part of) Bhatt--Morrow--Scholze's work on integral p-adic Hodge theory.

Please email Shubhodip or me if you would like to join the mailing list for this seminar.

This seminar is succeeded by its continuation here.


Tentative Plan

The seminar is divided into two parts. The first part concerns Sections 2-5 of [BMS19] (and relevant background), culminating in appreciation of Thm 1.17 of loc. cit. The second part aims at introducing relevant background for analogous concepts with a "topological" prefix, and hopefully by the end we get to the construction of the complex AΩ via THH.
