WebAccording to the standard definition, the De Rham cohomology of X°° is the cohomology of the complex of global sections m°Xoo - ríí^oo - ra^oo -> . . . However, because the QPXoo are fine sheaves, this is the same as the hyper-cohomology of the C°° De Rham complex H*dR(X°°) = H*(í&» - - n2xoo - . . .) In the analytic and algebraic ... Webany complex manifold, and Section 6 proves the algebraic de Rham theorem for a smooth complex projective variety. In Part II, we develop in Sections 7 and 8 the Cech cohomology of a sheaf and of aˇ complex of sheaves. Section 9 reduces the algebraic de Rham theorem for an algebraic variety to a theorem about afﬁne varieties.
