Abstract

After the ring theoretic study of differential operators in positive characteristic by S.U. Chase and S.P. Smith, B. Haastert started investigation of 𝒟-modules on smooth varieties in positive characteristic, and the work of R. Bøgvad followed. The purpose of this paper is to complement some basics for further study.
