Truncated Barsotti-Tate Groups and Truncated Displays

Truncated Barsotti-Tate Groups and Truncated Displays

Explore an advanced mathematics seminar presentation where Eike Lau delves into the intricate relationship between truncated Barsotti-Tate groups and truncated displays. Learn about the construction and properties of functors connecting these mathematical structures through crystalline Dieudonné theory. Understand the geometric properties of truncated Barsotti-Tate group stacks, with particular emphasis on the smoothness of truncation morphisms. The 2-hour 39-minute lecture, presented as part of the BunG Seminar series, provides a detailed mathematical exploration that complements Lau's research paper available on arXiv.
