During the winter term 2025/26 the research seminar will treat moduli stacks of formal groups, their applications to stable homotopy theory and recent connections to arithmetic geometry established by Barthel, Schlank, Stapleton and Weinstein.
Date and place: Thursday, 14:15-15:45 , WSC-N-U-3.05
First meeting: October 16, 2025
