DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CARTOON/3/">
 Newton strata in the weakly admissible locus</a>\nby Eva Viehmann as part 
 of Cross Atlantic Representation Theory and Other topics ONline (CARTOON) 
 conference\n\n\nAbstract\nGiven a reductive group $G$ over a $p$-adic loca
 l field and a minuscule cocharacter\, Rapoport and Zink constructed an ope
 n subspace inside the associated adic flag variety\, called $p$-adic perio
 d domain\, or weakly admissible locus. These are vast generalizations of D
 rinfeld upper half spaces. Recently\, Caraiani and Scholze defined a Newto
 n stratification on adic flag varieties. The unique open Newton stratum\, 
 which coincides with the so-called admissible locus\, is contained in the 
 weakly admissible locus\, but is in most cases strictly smaller. For the g
 roup $\\textnormal{GL}_n$\, I describe which of the other Newton strata in
 tersect the weakly admissible locus.\n
