Junior Chromatic Homotopy Theory Seminar


Max Blans, Sven van Nigtevecht, and I organized the Junior Chromatic Homotopy Theory Seminar where we covered the basic notions of chromatic homotopy theory, following Lurie's lecture series [1] on this matter. The seminar is aimed at starting PhD students, but interested master students familiar with the basics of stable homotopy theory are also welcome to join. Please drop me an e-mail if you would like to come to our seminar meetings!

Time & Location

The seminar will take place every Friday from 11.00-13.00. The location may change from time to time, see the schedule below.
