The Stacks of n-Truncated Barsotti-Tate Groups - Part 2

The Stacks of n-Truncated Barsotti-Tate Groups - Part 2

Explore foundational concepts of BT_n groups and n-smooth group schemes in this advanced mathematics seminar presented by Vladimir Drinfeld. Delve into the properties of group schemes over F_p-algebra R, with particular focus on n-smooth group schemes that are locally isomorphic to Spec R[x_1,…,x_d]/(x_1^{p^n},…, x_d^{p^n}) as based schemes. Learn about the relationship between commutative n-smooth group schemes and BT_n groups through detailed mathematical analysis and theoretical frameworks. Gain insights into the stacks of n-truncated Barsotti-Tate groups through this nearly two-hour academic presentation delivered as part of the BunG Seminar series on October 9, 2023.
