 ">Diamonds and p-adic period domains</a>\nby Xu Shen/申旭 (Morningside C
 enter of Mathematics\, AMSS) as part of ICCM 2020\n\n\nAbstract\nThe theor
 y of diamonds was introduced by Scholze in his 2014 Berkeley lectures\, wh
 ich provides a powerful tool to study p-adic Hodge theory and the Langland
 s program. In this talk\, we will investigate the geometry of some diamond
 s\, namely the B_{dR}^+-affine Schubert varieties\, via the Fargues-Fontai
 ne curve. Along the way\, the theory of p-adic period domains arises natur
 ally. We will explain how the de Rham periods and the Hodge-Tate periods a
 re related to each other\, and we will discuss the structure of certain ge
 neralized p-adic period domains.\n
