Tóm tắt: In 1987, Katz established an equivalence between differential modules over the field of formal Laurent series k((t)) and special differential modules over the multiplicative group over k, when k has characteristic 0. This result is a generalization of Deligne's equivalence between subcategories of regular singular differential modules. My talk will cover the p-adic analogue of both equivalences, which is a combination of results of Crew-Christol-Mebkhout-André-Matsuda.
