The Stacks of n-Truncated Barsotti-Tate Groups - Part 3

Explore a detailed mathematics seminar recording where Vladimir Drinfeld delves into n-smooth group schemes over F_p-schemes and their connection to BT_n groups during the third installment of his series on the Stacks of n-Truncated Barsotti-Tate Groups. Learn about the specific characteristics of group schemes G over an F_p-algebra R, particularly focusing on n-smooth conditions where schemes are locally isomorphic to Spec R[x_1,…,x_d]/(x_1^{p^n},…, x_d^{p^n}) as based schemes. Understand the relationship between commutative n-smooth group schemes and BT_n groups through this advanced mathematical discussion presented at the BunG Seminar on October 16, 2023.
