Note time and venue

Berthelot defines the sheaf of differential operators \widehat{D}X[m] of level m on a formal scheme X over a c.d.v.r. R of mixed characteristic (0, p). In this talk we prove there is an isomorphism between \widehat{D}X[1] and Mp(\widehat{D}X[0]) when X is the formal completion of AR1. If there is time we will study the global sections of \widehat{D}X[1] when X is the formal completion of PR1.

This talk is part of the Junior Algebra/Logic/Number Theory seminar series.
