Arithmetic đ-modules on the unit disk. With an appendix by Shigeki Matsuda

Abstract
Let đ± be a complete discrete valuation ring of mixed characteristic. We classify arithmetic đ-modules on Spf(đ±[[t]]) up to certain kind of âanalytic isomorphismâ. This result is used to construct canonical extensions (in the sense of Katz and Gabber) for objects of this category.
