 >A new approach to p-Hecke correspondences and Rapoport-Zink spaces</a>\nb
 y Keerthi Madapusi (Boston College) as part of FGC-HRI-IPM Number Theory W
 ebinars\n\n\nAbstract\nWe will present a new notion of isogeny between ‘
 p-divisible groups with additional structure’ that employs the cohomolog
 ical stacks of Drinfeld and Bhatt-Lurie—-in particular the theory of ape
 rtures developed in prior work with Gardner—-and combines it with some i
 nvariant theoretic tools familiar to the geometric Langlands and represent
 ation theory community\, namely the Vinberg monoid and the wonderful compa
 ctification. This gives a uniform construction of p-Hecke correspondeces a
 nd Rapoport-Zink spaces associated with unramified local Shimura data. In 
 particular\, we give the first general construction of RZ spaces associate
 d with exceptional groups. This work is joint with Si Ying Lee.\n
