Witt realization of \(p\)-adic Barsotti-Tate groups. (English) Zbl 0838.14038
Cristante, Valentino (ed.) et al., Barsotti symposium in algebraic geometry. Memorial meeting in honor of Iacopo Barsotti, in Abano Terme, Italy, June 24-27, 1991. San Diego, CA: Academic Press. Perspect. Math. 15, 65-123 (1994).
The authors give an extension of Barsotti’s theorem on “immersione canonica” to the case of a totally ramified extension of the ring of Witt vectors over an algebraically closed field of characteristic \(p > 0\) when the degree of ramification is less than \(p - 1\). They also clarify the meaning of some of the tools introduced by Barsotti in his study of \(p\)-adic Barsotti-Tate groups, in view of their use in the theory of the reduction of \(p\)-adic theta functions.
