WebDe nition 2.2. Let : X !X Y X be the diagonal morphism, which de nes a closed subscheme isomorphic to X in an open subset of X Y X. To this subscheme ( X) corresponds a sheaf of ideals I. We de ne the sheaf of di erentials as 1 X=Y:= 2(I=I). Remark. These two de nitions are compatible in the case where X and Y are a ne schemes De nition 2.3 ...

Webde Rham complex X=k of Xover k. This is a complex of abelian groups whose terms are coherent sheaves on X. The algebraic de Rham cohomology of Xis by de nition the hyper cohomology of this complex: H dR (X) := H(X; X=k): The hypercohomology of a bounded below complex of abelian sheaves is de ned in the appendix. Theorem. Assume khas ... Webanalytic stack. This result would be an immediate corollary of the main theorem, if the de Rham comparison theorem in p-adic Hodge theory would be valid for smooth and proper Deligne-Mumford stacks. This is the motivation for the present chapter. There are five parts. The first one (§§1–2)recalls certain facts about categories and
WebDe Rham's theorem gives an isomorphism of the first de Rham space H 1 ( X, C) ≅ C 2 g by identifying a 1 -form α with its period vector ( ∫ γ i α). Of course, the 19th century people would have been more interested in the case where α is holomorphic. Webwriteup discusses the de Rham cohomology, its basic properties, and the de Rham theorem. For the purposes of the assignment, the worked example is the calculation for …
