摘  要：It is conjectured by Scholze that a p-adic Shimura variety, viewed as a diamond, can be expressed as the fiber product of an adic flag variety and a so-called Igusa stack. This geometric structure has applications to understanding the cohomology of Shimura varieties and their integral models. I will explain these ideas and report on progress on this conjecture.
