Arithmetic 𝒟-modules on the unit disk. With an appendix by Shigeki Matsuda
Published online by Cambridge University Press: 09 November 2011
Abstract
Let 𝒱 be a complete discrete valuation ring of mixed characteristic. We classify arithmetic 𝒟-modules on Spf(𝒱[[t]]) up to certain kind of ‘analytic isomorphism’. This result is used to construct canonical extensions (in the sense of Katz and Gabber) for objects of this category.
