Tóm tắt: In this talk, I will prove an equivalence between the category of D-modules and that of D-crystals on a smooth scheme. Even though the concept of D-module can be extended over a singular schemes (Kashiwara's lemma), it is not easy to use in practice. The situation of D-crystal is better since its definition is intrinsic, hence, it has some advantages in dealing with singular schemes and formal schemes.
